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.

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.

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.

Insulin and Glucagon | Biology for All | FuseSchool
 
02:11
In this lesson, you will learn about how your blood glucose level is regulated (or controlled) by two important hormones – insulin and glucagon, via a negative feedback system. When you consume a meal that is high in carbohydrates, such as rice, pasta, and bread, this will cause your blood glucose level to increase. Carbohydrates are essentially long chains of repeating glucose monomer units, much like beads on a necklace. During digestion, this is broken apart into glucose, which absorbed into our bloodstream. This increased blood glucose level causes a gland known as the pancreas to secrete a hormone called insulin. Remember that a gland secretes hormones which act on specific target organs. In this case, the target organ is your liver, which is stimulated to convert glucose to glycogen. Glycogen is basically long, multi-branched chains of glucose monomers, stored in liver and muscle cells. Insulin also causes your body cells to uptake (or take in) glucose. So this decreases your blood glucose level back to its optimal state. When this system is faulty, this leads to a medical condition known as diabetes – If you want to learn more about diabetes, this will be addressed in another video. The same response also occurs when you consume foods and drinks high in sugar such as sweets, cakes, and fizzy drinks. When your blood glucose level drops, such as when you are hungry, the pancreas secretes a hormone called glucagon. Like insulin, the target organ for glucagon is also the liver, though it stimulates the opposite process – the breakdown of glycogen into glucose. This increases your blood glucose level back to its optimal state. So to review, insulin and glucagon are two hormones released by the pancreas, which act on the liver to regulate our blood glucose level.

Homeostatic Control Systems - Homeostatic Control Mechanisms and Feedback Control Loops
 
04:57
In this video we discuss what are homeostatic control systems and how they work. We cover feedback loops and how they work to help maintain homeostasis. Homeostatic control mechanisms or systems In order to maintain homeostasis cells must be in an environment that allows them to function properly with changing external conditions. Almost all of the organs and systems in the body must work to maintain homeostasis. If the body needs to change the internal environment it does so through what is called homeostatic control mechanisms. For instance, when you go for a run, your body needs more oxygen, and your body produces more carbon dioxide. So, the internal environment must adapt to the changing needs. During your run, your breathing will increase, bringing more oxygen in and eliminating the increased production of carbon dioxide, your heart beat and stroke volume will increase, thus increasing the amount of nutrient rich blood being sent throughout your body. This process of the body adjusting to a change is called a feedback control loop or feedback control system. These control loops transmit information in mainly 2 ways, through nervous impulses or by chemical messengers called hormones. Weather the nervous impulses or hormones are transmitting the information, the feedback control loops work in the same way and have the same basic components. The feedback control loops consist of 4 main components. A sensor mechanism, an integrator or control center, an effector mechanism and feedback. Hormone producing glands and sensory nerve cells can act as homeostatic sensors. If something changes outside of the normal set point range for homeostasis, a sensor transmits a signal to the next component of the feedback loop, the integrator. The integrator is the control center of the feedback loop and many times it is in an area of the brain. It gets this signal or variable and analyzes it and checks it with other signals or variables it has received from other sensors. It checks the value of the variables it has received against the normal set point range for those variables. If the integrator determines these variables are outside of the normal set point range, then, some type of action is needed. If action is necessary, the integrator sends a signal to the third component of the feedback control loop, the effector mechanism. Effectors are organs, like glands or muscles, which provide the response that the integrator, or control center desires. The goal of the effectors is to influence or change the values of the variables. This can be positive or negative changes to the variables, such as increasing or decreasing heart rate, or altering the concentration of glucose in the blood stream. Glucose being the main source of fuel for cells. As these effectors make changes, the variables attain new values, and this is sent back through the feedback control loop. For instance, if you are walking, then you start jogging, effectors will increase your heart rate, based on the mechanisms of the feedback control loop. Many sources use a diagram of a furnace controlled by a thermostat to explain this process more clearly. Here we have a house, and here we have a person. Let’s say that in both situations a stimulus happens, that being a cold front blows in, causing a decrease in temperature. The house has a thermometer, which is its sensor, and the person has temperature receptors in the skin, which are the sensor mechanism for the body. The thermometer sends the information that the temperature or variable has decreased, through wires to its integrator, the thermostat. The temperature receptors in the skin send the variable change through nerve fibers to the brain, or the integrator for the body in this situation. The integrators, or control centers for both the body and house, check the value of the newly received variables against the set point range that each of them has allowed for this type of variable. Since this temperature variable change does not lie in the set point range, the integrators send a signal to effectors to do something to get these variables within this set point range. In the case of the house the thermostat sends a message through wires to the furnace to crank the heat up. In the body, the brain sends a message through nerve fibers to the muscles to start shivering to generate some heat. In both the house and the body of the person, the heat that is generated brings them both to a state of homeostasis. Once homeostasis is reached, both sensor mechanisms, the thermometer and temperature receptors in the skin are sending new variable values, or feedback to their integrators that lie within the set point ranges. One note, homeostatic control systems can be based on positive or negative feedback.

Transport Across Cell Membranes
 
13:58
016 - Transport Across Cell Membranes Paul Andersen describes how cells move materials across the cell membrane. All movement can be classified as passive or active. Passive transport, like diffusion, requires no energy as particles move along their gradient. Active transport requires additional energy as particles move against their gradient. Specific examples, like GLUT and the Na/K pump are included. Do you speak another language?

kidney structure and nephron function in filtration in urine formation
 
18:42
Structure And Function Of Kidney And Nephron In Hindi | Vinay Rajput csir net life science lectures . In this lecture we discuss about the Structure And Function Of Kidney and Structure And Function Of nephron . The kidneys are two bean-shaped organs found on the left and right sides of the body in vertebrates. They filter the blood in order to make urine, to release and retain water, and to remove waste and nitrogen (the excretory system).The kidneys regulate the balance of ions known as electrolytes in the blood, along with maintaining acid base homeostasis. They also move waste products out of the blood and into the urine, such as nitrogen-containing urea and ammonium. Kidneys also regulate fluid balance and blood pressure. They are also responsible for the reabsorption of water, glucose, and amino acids. The kidneys also produce hormones including calcitriol and erythropoietin. The kidneys also make an important enzyme, renin, which affects blood pressure through negative feedback. n humans, the kidneys are located high in the abdominal cavity, one on each side of the spine, and lie in a retroperitoneal position at a slightly oblique angle. The kidney has a bean-shaped structure with a convex and a concave border. A recessed area on the concave border is the renal hilum, where the renal artery enters the kidney and the renal vein and ureter leave. Renal histology studies the microscopic structure of the kidney. Distinct cell types include: Kidney glomerulus parietal cell Kidney glomerulus podocyte Kidney proximal tubule brush border cell Loop of Henle thin segment cell Thick ascending limb cell Kidney distal tubule cell Collecting duct principal cell Collecting duct intercalated cell Interstitial kidney cells Early proximal tubule Thin descending loop of Henle Thick ascending loop of Henle Early distal convoluted tubule Collecting tubules The nephron is the basic structural and functional unit of the kidney. Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine. A nephron eliminates wastes from the body, regulates blood volume and blood pressure, controls levels of electrolytes and metabolites, and regulates blood pH. Its functions are vital to life and are regulated by the endocrine system by hormones such as antidiuretic hormone, aldosterone, and parathyroid hormone. In humans, a normal kidney contains 800,000 to 1.5 million nephrons.

He uses thermoregulation in mammals to explain how a negative feedback loop functions. He uses fruit ripening to explain how a positive feedback loop functions. He also explains what can happen when a feedback look is altered. Diabetes mellitus is caused by an alteration in the blood glucose feedback loop. Do you speak another language?

Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia The kidneys filter blood plasma, removing metabolic wastes, toxins from the body and excrete them in the form of urine. During this process, they also maintain constant volume and composition of the blood, or homeostasis. Blood enters the kidney via the renal artery, which divides to smaller arteries and finally arterioles. The arterioles get into contact with functional units of the kidney called nephrons. This is where blood filtration and urine formation take place. The filtered blood is then collected in to a series of larger veins and exits the kidney through the renal vein. The urine is collected in collecting ducts and leaves the kidney via the ureters. A nephron consists of 2 major parts: Bowman’s capsule; and a long renal tubule. Renal tubules of several nephrons connect to a common collecting duct. There are 3 steps in the formation of urine: glomerular filtration, tubular reabsorption and secretion, water conservation. Blood enters the Bowman’s capsule via the afferent arteriole, passes through a ball of capillaries called the glomerulus, and leaves via the efferent arteriole. Hydrostatic and osmotic pressures drive water and solutes from blood plasma through a filtration membrane into the capsular space of nephron. These include water, inorganic ions, glucose, amino acids and various metabolic wastes such as urea and creatinine. The amount of filtrate produced per minute is called glomerular filtration rate, or GFR. The GFR is kept at a stable value by several feedback mechanisms within the kidneys. This is known as renal autoregulation. The GFR is also under sympathetic and hormonal control. The proximal convoluted tubule, reabsorbs about two thirds of the filtrate. In this process, water and solutes are driven through the epithelial cells that line the tubule into the extracellular space. They are then taken up by the peritubular capillaries. Sodium re-absorption is most important, as it creates osmotic pressure that drives water and electrical gradient that drives negatively charged ions. Sodium level inside the epithelial cells is kept low thanks to the sodium-potassium pumps that constantly pump sodium ions out into the extracellular space. This creates a concentration gradient that favors sodium diffusion from tubular fluid into the cells. Sodium is absorbed by symport proteins that also bind glucose and some other solutes. About half of nitrogenous wastes also re-absorbs back to the bloodstream. Some of the re-absorption also occurs by the paracellular route through tight junctions between the epithelial cells. At the same time, tubular secretion also takes place. The main function of the loop of Henle is to create and maintain an osmolarity gradient in the medulla that enables the collecting ducts to concentrate urine at a later stage. The ascending limb of the loop actively pumps sodium out making the medulla “salty”. The descending limp of the loop is permeable to water but much less to sodium. As the water exits the tubule by osmosis, the filtrate gets more and more concentrated as it reaches the bottom. The ascending limb, on the other hand, is permeable to ions but not water. As a result, the filtrate loses sodium as it goes up and becomes more diluted at the top of the loop. Re-absorption and secretion in the distal convoluted tubule are under control of various hormones. The main function of the collecting duct is to concentrate urine and therefore conserve water. As it gets saltier deep in the medulla, the filtrate loses more and more water as it flows down the collecting duct. The collecting duct is also under hormonal control so it can adjust the amount of re-absorbed water accordingly to the body’s state of hydration.
