How Blood Pressure Works Animation - Understanding Blood Pressure Measurement Monitor Readings Video

Normal blood pressure is important for proper blood flow to the body’s organs and tissues. The force of the blood on the walls of the arteries is called blood pressure. Blood pressure is measured both as the heart contracts, which is called systole, and as it relaxes, which is called diastole. Normal blood pressure is considered to be a systolic blood pressure of 115 millimeters of mercury a diastolic pressure of 70 millimeters of mercury (stated as "115 over 70"). If an individual were to have a consistent blood pressure reading of 140 over 90, he would be evaluated for having high blood pressure. If left untreated, high blood pressure can damage important organs, such as the brain and kidneys, as well as lead to a stroke. High blood pressure is a common disease in which blood flows through blood vessels (arteries) at higher than normal pressures. Measuring Blood Pressure Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood. High blood pressure, sometimes called hypertension, happens when this force is too high. Health care workers check blood pressure readings the same way for children, teens, and adults. They use a gauge, stethoscope or electronic sensor, and a blood pressure cuff. With this equipment, they measure: Systolic Pressure: blood pressure when the heart beats while pumping blood Diastolic Pressure: blood pressure when the heart is at rest between beats Health care workers write blood pressure numbers with the systolic number above the diastolic number. For example: 118/76 mmHg People read "118 over 76" millimeters of mercury. Normal Blood Pressure: Normal blood pressure for adults is defined as a systolic pressure below 120 mmHg and a diastolic pressure below 80 mmHg. It is normal for blood pressures to change when you sleep, wake up, or are excited or nervous. When you are active, it is normal for your blood pressure to increase. However, once the activity stops, your blood pressure returns to your normal baseline range. Blood pressure normally rises with age and body size. Newborn babies often have very low blood pressure numbers that are considered normal for babies, while older teens have numbers similar to adults. Abnormal Blood Pressure Abnormal increases in blood pressure are defined as having blood pressures higher than 120/80 mmHg. The following table outlines and defines high blood pressure severity levels. The ranges in the table are blood pressure guides for adults who do not have any short-term serious illnesses. People with diabetes or chronic kidney disease should keep their blood pressure below 130/80 mmHg. Although blood pressure increases seen in prehypertension are less than those used to diagnose high blood pressure, prehypertension can progress to high blood pressure and should be taken seriously. Over time, consistently high blood pressure weakens and damages your blood vessels, which can lead to complications. Types of High Blood Pressure There are two main types of high blood pressure: primary and secondary high blood pressure. Primary High Blood Pressure Primary, or essential, high blood pressure is the most common type of high blood pressure. This type of high blood pressure tends to develop over years as a person ages. Secondary High Blood Pressure Secondary high blood pressure is caused by another medical condition or use of certain medicines. This type usually resolves after the cause is treated or removed. Blood pressure (BP) is the pressure exerted by circulating blood upon the walls of blood vessels. When used without further specification, "blood pressure" usually refers to the arterial pressure in the systemic circulation. It is usually measured at a person's upper arm. Blood pressure is usually expressed in terms of the systolic (maximum) pressure over diastolic (minimum) pressure and is measured in millimeters of mercury (mm Hg). It is one of the vital signs along with respiratory rate, heart rate, oxygen saturation, and body temperature. Normal resting blood pressure in an adult is approximately 120/80 mm Hg. Blood pressure varies depending on situation, activity, and disease states. It is regulated by the nervous and endocrine systems. Blood pressure that is low due to a disease state is called hypotension, and pressure that is consistently high is hypertension. Both have many causes which can range from mild to severe. Both may be of sudden onset or of long duration. Long term hypertension is a risk factor for many diseases, including kidney failure, heart disease, and stroke. Long term hypertension is more common than long term hypotension in Western countries. Long term hypertension often goes undetected because of infrequent monitoring and the absence of symptoms. Physiology: During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure. Q. What blood pressure should I have? What is normal blood pressure?

Baroreflex Regulation of Blood Pressure, Animation.

How heart rate is controlled by the parasympathetic and sympathetic divisions of the autonomic nervous system, with overview of baroreceptor resetting.

All rights reserved. Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia Baroreflex, or baroreceptor reflex, is one of the mechanisms the body uses to maintain stable blood pressure levels or homeostasis. Baroreflex is a rapid negative feedback loop in which an elevated blood pressure causes heart rate and blood pressure to decrease. Reversely, a decrease in blood pressure leads to an increased heart rate, returning blood pressure to normal levels. The reflex starts with specialized neurons called baroreceptors. These are stretch receptors located in the wall of the aortic arch and carotid sinus. Increased blood pressure stretches the wall of the aorta and carotid arteries causing baroreceptors to fire action potentials at a higher than normal rate. These increased activities are sent via the vagus and glossopharyngeal nerves to the nucleus of the tractus solitarius – the NTS - in the brainstem. In response to increased baroreceptor impulses, the NTS activates the parasympathetic system – the PSNS - and inhibits the sympathetic system – the SNS. As the PSNS and SNS have opposing effects on blood pressures, PSNS activation and SNS inhibition work together in the same direction to maximize blood pressure reduction. Parasympathetic stimulation decreases heart rate by releasing acetylcholine which acts on the pacemaker cells of the SA node. Inhibition of the sympathetic division decreases heart rate, stroke volume and at the same time causes vasodilation of blood vessels. Together, these events rapidly bring DOWN blood pressure levels back to normal. When a person has a sudden drop in blood pressure, for example when standing up, the decreased blood pressure is sensed by baroreceptors as a decrease in tension. Baroreceptors fire at a lower than normal rate and the information is again transmitted to the NTS. The NTS reacts by inhibiting parasympathetic and activating sympathetic activities. The sympathetic system releases norepinephrine which acts on the SA node to increase heart rate; on cardiac myocytes to increase stroke volume and on smooth muscle cells of blood vessels to cause vasoconstriction. Together, these events rapidly bring UP blood pressure levels back to normal. Baroreflex is a short-term response to sudden changes of blood pressure resulted from everyday activities and emotional states. If hypertension or hypotension persists for a long period of time, the baroreceptors will reset to the “new normal” levels. In hypertensive patients for example, baroreflex mechanism is adjusted to a higher “normal” pressure and therefore MAINTAINS hypertension rather than suppresses it.

What is PULSE? | Meaning, Definition, Explaination in HIndi | Bhushan Science
 
07:36
PULSE It is a wave of pulse on the arterial vessels wall generated as a result of expansion and elongation of the wall during ventricular systole and diastole. The pulse is a wave of distension and elongation felt in an artery wall due to the contraction of the left ventricle forcing about 60 to 80 millilitres of blood through the already full aorta and into the arterial system. When the aorta is distended, a wave passes along the walls of the arteries and can be felt at any point where a superficial artery can be pressed gently against a bone. The number of pulse beats per minute normally represents the heart rate and varies considerably in different people and in the same person at different times. An average of 60 to 80 is common at rest. Information that may be obtained from the pulse includes: The rate at which the heart is beating. The regularity with which the heart beats occur, i.e. the length of time between beats should be the same. The volume or strength of the beat —it should be possible to compress the artery with moderate pressure, stopping the flow of blood; the compressibility of the blood vessel gives some indication of the blood pressure and the state of the blood vessel wall. The tension — the artery wall should feel soft and pliant under the fingers. Share, Support, Subscribe!!!

Hypertension - Definition, Causes, Symptoms and Treatment options
 
06:31
Hypertension - Definition, Causes, Symptoms and Treatment options In this week's video, I will be going over hypertension (high blood pressure), I will be talking about how to define hypertension, how hypertension is diagnosed, the causes of hypertension, the symptoms of hypertension and what are the certain treatment options for hypertension. Hypertension (AKA High blood pressure) is quite literally what it says on the tin, it's having the pressure in your blood vessels be too high. The normal range of blood pressure is 90-119 for systolic and 60-69 for diastolic. Hypertension can be divided into two groups, the majority of people fall into the first category, which is known as primary hypertension, this type doesn't have a cure and is a result of age and lifestyle choices. Most symptoms of hypertension do not manifest until, the pressure is very high, causing it to be known as the silent killer. When assessing a patient with newly diagnosed hypertension, you need to check that there is no damage to the organs mentioned above, 3 investigations that need to be done are funduscopic to check for any retinopathy, Urine dipstick to check for renal disease, ECG to check for left ventricular hypertrophy and Ischemic heart disease. HbA1c to check for diabetes as that is an important risk factor for cardiovascular disease and check lipids for similar reasons. The first type of treatment of hypertension is lifestyle changes, such as losing weight, exercising, eating less salt, stopping smoking etc. In terms of the medications the main classes I will speak about are diuretics, ACE inhibitors, Angiotensin 2 receptor antagonists, calcium channel blockers Blood pressure is calculated as flow (that is the volume of fluid in your vessels) times resistance. So higher flow or higher resistance leads to a higher blood pressure, as a result, most blood pressure medications work to lower either flow or resistance and thus lower blood pressure. DIruretics increase salt and water excretion, so lower the fluid volume in the body. ACE inhibitors interfere with the renin-angiotensin, aldosterone system. they stop the formation of angiotensin 2 which is a vasoconstrictor. not only that but without angiotensin 2 there is less aldosterone which normally helps to retain sodium and water, so ACE inhibitors lower resistance and flow Angiotensin 2 receptor blockers, these work in a similar fashion to ACE I but rather than stop the formation of angiotensin 2, they block the receptors for angiotensin 2. Calcium channel blockers block channels in the smooth muscles of your blood vessels, calcium normally causes these vessels to contract, so if they are blocked, the vessels will relax and have lower resistance Treatment: Step 1 less than 55 give ACEi (or ARB if can tolerate ACE), over 55 or if black give CCB (or Diuretic if can't tolerate) Step 2 CCB + ACEi/ ARB (never use ACEi and ARB together ) Step 3 ACEi/ ARBS + CCB + diuretic Sources: http://bestpractice.bmj.com/best-practice/monograph/26/treatment/step-by-step.html Passmedicine Oxford handbook of clinical medicine nice.org.uk FOLLOW ME Twitter and Instagram: Medic_Ene Twitter: https://twitter.com/Medic_Ene Instagram: https://www.instagram.com/medic_ene/ MedicEne provides a fun and different view of medical problems among other things, hope you enjoy it!

High Blood Pressure: Definition and Treatment
 
02:03
High blood pressure is a consistent reading of 140/90 or higher. Bethany Panchal, MD, a Family Medicine physician with Ohio State’s Wexner Medical Center, defines “consistent” as two or more readings taken days apart. When high blood pressure is considered borderline—or near that 140/90 range—changes in diet and exercise may be sufficient to lower readings. This can include a DASH or low salt diet. When readings are higher, at 150-160 range or above, medication may be added to lifestyle changes. Proper treatment is important, as high blood pressure increases the risk of heart attack, stroke and even blindness.

HIGH BLOOD PRESSURE | HYPERTENSION | HIGH BLOOD PRESSURE SYMPTOMS AND TREATMENT IN URDU/HINDI HIGH BLOOD PRESSURE: High blood pressure is also known as hypertension, caused by the increase in blood circulation in the body. If it is not treated on time, it can cause brain haemorrhage, coma and even death. For this reason it is vital that it be taken proper care of. The most important thing to know about high blood pressure control what it exactly it, what causes and what are the ways to treat this health condition. Heart Pumping and Blood Pressure: Human body contains 5-6 liters of blood depending on the sex and age. Almost 5 liters of blood passes through the heart and is purified every second. Heart separates deoxygenated blood from oxygenated blood, send the deoxygenated blood to the lungs for getting oxygen and the oxygenated blood to all part of the body. This process is done by the contraction & relaxation of the heart muscles, each cycle called a heart beat. After purifying the blood, it delivers the blood to all body parts through veins and arteries. The amount of heart beats depends on the flow of blood from the heart. If the pressure of blood flow is high, the heart beat rate will also be higher. Same is the other way around. This increased or decreased blood pressure causes the veins & valves to contract and expand accordingly putting pressure on the blood vessels and the heart. Symptoms: Headache Vomit Low energy level Weak eye sight Improper working of digestive system How to measure the blood pressure & its diagnosis: The first step in high blood pressure treatment is diagnosing whether a patient has high BP of low. If the blood circulation is 140 / 90 torr or higher, then it will be categorized as high blood pressure. 139 / 89 torr pressure is known as pre-hyper tension, which indicates that it is the starting point of blood pressure. Diagnosis process needs to be carried according to following parameters: Sample should be examined three times in a week. If the blood pressure of the patient is very high then one should wait for half hour then check the blood pressure again. The blood pressure is measured with a strip and from upper part of arm. BP is measured in “mmhg”, which is known as Cardiac Output or heart rate; increased heart rate indicates high blood pressure. According to the American Heart Association blood pressure in measured in two parameters; Dialectic mmhg and Systolic mmhg. In a healthy human being, the level of systolic & dialectic blood mmhg should be according to the following figures. Systolic mmhg: hypertension 90, 90 – 119 Dialectic mmhg: hypertension 60, 60 – 79 High Blood Pressure Treatment: It important to avoid the things that cause high blood pressure in the first place. Hypertension is divided into five stages, first two stages are not very dangerous and by self precautions, you can prevent severe hypertension. At this stage patient should avoid foods with high fats, smoking & exercise regularly. Salt is the main cause of high blood pressure and drug therapy & Beta blockers are suggested for the patients. Eating a healthy diet and emphasizing on natural diet like fruits and vegetables can help control blood pressure a lot. If you have developed High BP, it is very important that you get checkup every now and then. Lastly, it depends on you that how much you are willing to control hypertension. Take things lightly, take exercise, take some time out for yourself away from routine life, go out with friends and add fun to your life. You won’t even know when you came out of it.

Blood pressure Blood pressure: The blood pressure is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle. It's measurement is recorded by two numbers. The first (systolic pressure) is measured after the heart contracts and is highest. The second (diastolic pressure) is measured before the heart contracts and lowest. A blood pressure cuff is used to measure the pressure. Elevation of blood pressure is called hypertension.

What is PULSE? What does PULSE mean? PULSE meaning - PULSE pronunciation - PULSE definition - PULSE explanation - How to pronounce PULSE? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In medicine, a pulse represents the tactile arterial palpation of the heartbeat by trained fingertips. The pulse may be palpated in any place that allows an artery to be compressed against a bone, such as at the neck (carotid artery), on the inside of the elbow (brachial artery), at the wrist (radial artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint (posterior tibial artery), and on foot (dorsalis pedis artery). Pulse (or the count of arterial pulse per minute) is equivalent to measuring the heart rate. The heart rate can also be measured by listening to the heart beat directly (auscultation), traditionally using a stethoscope and counting it for a minute. The radial pulse is commonly measured using three fingers. This has a reason: the finger closest to the heart is used to occlude the pulse pressure, the middle finger is used get a crude estimate of the blood pressure, and the finger most distal to the heart (usually the ring finger) is used to nullify the effect of the ulnar pulse as the two arteries are connected via the palmar arches (superficial and deep). The study of the pulse is known as sphygmology. The pulse is a decidedly low tech and high yield and antiquated term still useful at the bedside in an age of computational analysis of cardiac performance. Claudius Galen was perhaps the first physiologist to describe the pulse. The pulse is an expedient tactile method of determination of systolic blood pressure to a trained observer. Diastolic blood pressure is non-palpable and unobservable by tactile methods, occurring between heartbeats. Pressure waves generated by the heart in systole move the arterial walls. Forward movement of blood occurs when the boundaries are pliable and compliant. These properties form enough to create a palpable pressure wave. The heart rate may be greater or lesser than the pulse rate depending upon physiologic demand. In this case, the heart rate is determined by auscultation or audible sounds at the heart apex, in which case it is not the pulse. The pulse deficit (difference between heart beats and pulsations at the periphery) is determined by simultaneous palpation at the radial artery and auscultation at the heart apex. It may be present in case of premature beats or atrial fibrillation. Pulse velocity, pulse deficits and much more physiologic data are readily and simplistically visualized by the use of one or more arterial catheters connected to a transducer and oscilloscope. This invasive technique has been commonly used in intensive care since the 1970s. The rate of the pulse is observed and measured by tactile or visual means on the outside of an artery and is recorded as beats per minute or BPM. The pulse may be further indirectly observed under light absorbances of varying wavelengths with assigned and inexpensively reproduced mathematical ratios. Applied capture of variances of light signal from the blood component hemoglobin under oxygenated vs. deoxygenated conditions allows the technology of pulse oximetry. A normal pulse is regular in rhythm and force. An irregular pulse may be due to sinus arrhythmia, ectopic beats, atrial fibrillation, paroxysmal atrial tachycardia, atrial flutter, partial heart block etc. Intermittent dropping out of beats at pulse is called "intermittent pulse". Examples of regular intermittent (regularly irregular) pulse include pulsus bigeminus, second-degree atrioventricular block. An example of irregular intermittent (irregularly irregular) pulse is atrial fibrillation. It corresponds to diastolic blood pressure. A low tension pulse (pulsus mollis), the vessel is soft or impalpable between beats. In high tension pulse (pulsus durus), vessels feels rigid even between pulse beats. A form or contour of a pulse is palpatiory estimation of arteriogram. A quickly rising and quickly falling pulse (pulsus celer) is seen in aortic regurgitation. A slow rising and slowly falling pulse (pulsus tardus) is seen in aortic stenosis.

A review of 1.25 million medical records of 30 year olds and older from a primary care practice for 5 years in England and looked at the different effects of systolic and diastolic blood pressure when it came to intracerebral bleeds, angina, abdominal aortic aneurysm, and renal disease. They published their results in the May issue of the journal The Lancet. It was discovered that in a 30 year old with hypertension the lifetime risk for developing cerebrovascular disease was 63% compared to 46% in those with normal blood pressure. They also found that those with hypertension developed cardiovascular disease about 5 years sooner.

High blood pressure High blood pressure: A repeatedly elevated blood pressure exceeding 140 over 90 mmHg. Chronic high blood pressure can stealthily cause blood vessel changes in the back of the eye (retina), abnormal thickening of the heart muscle, kidney failure, and brain damage. No specific cause for high blood pressure is found in 95 percent of patients. Treatment for high blood pressure involves dietary changes, regular aerobic exercise, and medication. There are many types of medications used to treat high blood pressure including diuretics, beta-blockers, blood vessel dilators, and others. Also known as hypertension.

High and Low Blood Pressure Symptoms and Precautions in Hindi
 
14:19
Blood pressure (BP) is the pressure exerted by circulating blood upon the walls of blood vessels. When used without further specification, "blood pressure" usually refers to the arterial pressure in the systemic circulation. It is usually measured at a person's upper arm. Blood pressure is usually expressed in terms of the systolic (maximum) pressure over diastolic (minimum) pressure and is measured in millimeters of mercury (mm Hg). It is one of the vital signs along with respiratory rate, heart rate, oxygen saturation, and body temperature. Normal resting blood pressure in an adult is approximately 120/80 mm Hg. Blood pressure varies depending on situation, activity, and disease states. It is regulated by the nervous and endocrine systems. Blood pressure that is low due to a disease state is called hypotension, and pressure that is consistently high is hypertension. Both have many causes which can range from mild to severe. Both may be of sudden onset or of long duration. Long term hypertension is a risk factor for many diseases, including kidney failure, heart disease, and stroke. Long term hypertension is more common than long term hypotension in Western countries. Long term hypertension often goes undetected because of infrequent monitoring and the absence of symptoms.

Regulation of Blood Pressure (Short & Long Term Regulation) in Hindi | Bhushan Science
 
37:08
The cardiovascular system is subject to precise reflex regulation so that an appropriate supply of oxygenated blood can be reliably provided to different body tissues under a wide range of circumstances. The sensory monitoring for this critical homeostatic process entails primarily mechanical (barosensory) information about pressure in the arterial system and, secondarily, chemical (chemosensory) information about the level of oxygen and carbon dioxide in the blood. The parasympathetic and sympathetic activity relevant to cardiovascular control is determined by the information supplied by these sensors. The mechanoreceptors (called baroreceptors) are located in the heart and major blood vessels; the chemoreceptors are located primarily in the carotid bodies, which are small, highly specialized organs located at the bifurcation of the common carotid arteries (some chemosensory tissue is also found in the aorta). The nerve endings in baroreceptors are activated by deformation as the elastic elements of the vessel walls expand and contract. The chemoreceptors in the carotid bodies and aorta respond directly to the partial pressure of oxygen and carbon dioxide in the blood. Both afferent systems convey their status via the vagus nerve to the nucleus of the solitary tract, which relays this information to the hypothalamus and the relevant brainstem tegmental nuclei (located in brain stem). The afferent information from changes in arterial pressure and blood gas levels reflexively modulates the activity of the relevant visceral motor pathways and, ultimately, of target smooth and cardiac muscles and other more specialized structures. For example, a rise in blood pressure activates baroreceptors that, inhibit the tonic activity of sympathetic preganglionic neurons in the spinal cord. In parallel, the pressure increase stimulates the activity of the parasympathetic preganglionic neurons in the dorsal motor nucleus of the vagus and the nucleus ambiguus that influence heart rate. The carotid chemoreceptors also have some influence, but this is a less important drive than that stemming from the baroreceptors. As a result of this shift in the balance of sympathetic and parasympathetic activity, the stimulatory noradrenergic effects of postganglionic sympathetic innervation on the cardiac pacemaker and cardiac musculature is reduced (an effect abetted by the decreased output of catecholamines from the adrenal medulla and the decreased vasoconstrictive effects of sympathetic innervation on the peripheral blood vessels). At the same time, activation of the cholinergic parasympathetic innervation of the heart decreases the discharge rate of the cardiac pacemaker in the sinoatrial node and slows the ventricular conduction system. These parasympathetic influences are mediated by an extensive series of parasympathetic ganglia in and near the heart, which release acetylcholine onto cardiac pacemaker cells and cardiac muscle fibers. As a result of this combination of sympathetic and parasympathetic effects, heart rate and the effectiveness of the atrial and ventricular mycoardial contraction are reduced and the peripheral arterioles dilate, thus lowering the blood pressure. In contrast to this sequence of events, a drop in blood pressure, as might occur from blood loss, has the opposite effect, inhibiting parasympathetic activity while increasing sympathetic activity. As a result, norepinephrine is released from sympathetic postganglionic terminals, increasing the rate of cardiac pacemaker activity and enhancing cardiac contractility, at the same time increasing release of catecholamines from the adrenal medulla (which further augments these and many other sympathetic effects that enhance the response to this threatening situation). Norepinephrine released from the terminals of sympathetic ganglion cells also acts on the smooth muscles of the arterioles to increase the tone of the peripheral vessels, particularly those in the skin, subcutaneous tissues, and muscles, thus shunting blood away from these tissues to those organs where oxygen and metabolites are urgently needed to maintain function (e.g., brain, heart, and kidneys in the case of blood loss). If these reflex sympathetic responses fail to raise the blood pressure sufficiently (in which case the patient is said to be in shock), the vital functions of these organs begin to fail, often catastrophically.

Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia CARDIAC OUTPUT is the amount of blood pumped by each ventricle in one minute. It is the product of STROKE VOLUME – the amount of blood pumped in one heartbeat, and HEART RATE – the number of beats in one minute. An INcrease in either stroke volume or heart rate results in INcreased cardiac output, and vice versa. For example, during physical exercises, the heart beats faster to put out more blood in response to higher demand of the body. It is noteworthy that the ventricles do NOT eject ALL the blood they contain in one beat. In a typical example, a ventricle is filled with about 100ml of blood at the end of its load, but only 60ml is ejected during contraction. This corresponds to an EJECTION fraction of 60%. The 100ml is the end-DIASTOLIC volume, or EDV. The 40ml that remains in the ventricle after contraction is the end-SYSTOLIC volume, or ESV. The stroke volume equals EDV minus ESV, and is dependent on 3 factors: contractility, preload, and afterload. Contractility refers to the force of the contraction of the heart muscle. The more forceful the contraction, the more blood it ejects. PRELOAD is RELATED to the end-diastolic volume. Preload, by definition, is the degree of STRETCH of cardiac myocytes at the end of ventricular filling, but since this parameter is not readily measurable in patients, EDV is used instead. This is because the stretch level of the wall of a ventricle INcreases as it’s filled with more and more blood; just like a balloon - the more air it contains, the more stretched it is. According to the Frank-Starling mechanism, the greater the stretch, the greater the force of contraction. In the balloon analogy, the more inflated the balloon, the more forceful it releases air when deflated. AFTERLOAD, on the other hand, is the RESISTANCE that the ventricle must overcome to eject blood. Afterload includes 2 major components: - Vascular pressure: The pressure in the left ventricle must be GREATER than the systemic pressure for the aortic valve to open. Similarly, the pressure in the right ventricle must exceed pulmonary pressure to open the pulmonary valve. In hypertension for example, higher vascular pressures make it more difficult for the valves to open, resulting in a REDUCED amount of ejected blood. - Damage to the valves, such as stenosis, also presents higher resistance and leads to lower blood output.

Renin Angiotensin Aldosterone System
 
03:43
This animation focuses on the renin angiotensin aldosterone system (RAAS), a classic endocrine system that helps to regulate long-term blood pressure and extracellular volume in the body. Many aspects of cardiovascular disease progression can be directly linked to the RAAS system. Mechanisms such as vascular inflammation, generation of reactive oxygen species and alterations of endothelial function are all known to play a role in atherosclerosis.
