See more @ http://cteskills.com The cardiovascular system, also known as the circulatory system, is the transportation system of the body. The major structures that make this possible are the heart, blood vessels and blood. Simply put, the heart pumps the blood in order to move nutrients through the blood vessels to nourish and to remove metabolic wastes from the body. The purpose of this video is to present a basic understanding of the Cardiovascular System. A more in depth study of the system will be presented in other CTE videos where we will look into each specific structure and function of the Cardiovascular system. A, The pulmonary pathway B. The Systemic pathway Two Atria - which are the upper chambers. Two ventricles - these are the lower chambers The left and right side of the heart is divided by the SEPTUM Blood Vessels The word vessel has many meanings but in Anatomy and Physiology, Blood Vessels are meant for carrying or transporting the blood throughout the body. Arterioles are smaller blood vessels that branch out from larger arteries and lead to the (arterial) capillaries, which are the smallest blood vessels in the body… The arterial capillaries are connected to the venous capillaries…The arterial side of the capillaries is dropping off Oxygen and Nutrients TO the body’s cells The venous side of the capillaries is picking up metabolic waste FROM the body’s cells together they form a network, where arteries and veins connect completing the (closed) circulatory circuit, ….the blood flow from the venous capillaries will flow back from the body TO the heart through venous blood vessels. Similar to the arteries, only in reverse, the blood flows from the venous capillaries into a system of veins called the VENULES . These venules connect to larger veins which carry the blood back FROM the Body TO the heart, VIA the largest veins known as the Superior and Inferior Vena Cavas... The first type of blood cell is called Erythrocyte. known as the red blood cell. 2. the second type of blood cell is the Leukocyte.. known as the white blood cell 3....and the third type of cell is the thrombocytes, also known as the platelet The SA node, known as the pacemaker, is located in the right atria. It starts the spark and passes it on to the next relay station. The AV node which is located on the back wall of the heart between the right atria and the right ventricle. The spark is then passed unto the...next relay station… the ... Bundle of HIS located in the heart’s septum...and then lastly to the purjinke fibers, the relay station which spreads the electrical charge throughout the myocardium, which is the cardiac muscle, and causes the heart to contract; atrias first then the ventricles... After watching this video, you should now have a basic understanding of what the Cardiovascular System is, the basic functions, and the basic structures that define the HEART. Here’s a quick recap. The Cardiovascular or Circulatory System is an organ system whose basic purpose is to circulate blood to and from cells in the body in order to transport nutrients and remove waste. The heart pumps the blood TO the body through arteries which branch off into smaller blood vessels called arterioles. The Network of capillaries is where oxygen and other nutrients diffuse from the blood and into the cells. As O2 and nutrients are diffused into the cells from the arterial capillaries, metabolic waste is diffused into the venous capillaries from the cells...the blood returns to the heart via the veins where the cycle begins again. And remember that the heart has a beat of its own, through the electro/chemical circuit system and its 4 relay stations To sum it all up, the heart pumps blood to the BODY through the arteries and returns FROM the Body to the heart through the veins. Unfortunately, The heart is also subject to diseases and conditions … in fact the number one reason for an early demise is still due to heart failure.. These conditions will be discussed further in future CTE videos.

How The Circulatory System Works - Functions Of The Cardiovascular System - Path Of Blood Flow
 
01:06
In this video I discuss the circulatory system or cardiovascular system, the functions of the cardiovascular system and the path of blood flow through the heart and components of the cardiovascular system. Transcript (partial with notes) The circulatory system is responsible for transporting nutrients, such as, hormones, water, oxygen and other nutrients to and from virtually all cells throughout the body. It also carries away carbon dioxide and other waste materials produced by cells. The cardiovascular system is made up of the heart, vessels, which include arteries, veins and capillaries. Let’s look at the path of nutrients though the body… 1st, Oxygen is absorbed in the lungs, where it enters the bloodstream and goes to the heart, which pumps it into arteries. Arteries take the oxygenated material to organs and tissues, where they merge into capillaries. Many capillaries enter tissue to form a capillary bed. The oxygenated material drops off its nutrients, and collects waste materials such as carbon dioxide. This deoxygenated waste continues through the capillary which merge into veins. The veins then take the waste to the heart, which pumps it back to the lungs where it can get oxygenated again.

Your heart gets a lot of attention from poets, songwriters, and storytellers, but today Hank's gonna tell you how it really works. The heart’s ventricles, atria, and valves create a pump that maintains both high and low pressure to circulate blood from the heart to the body through your arteries, and bring it back to the heart through your veins. You'll also learn what your blood pressure measurements mean when we talk about systolic and diastolic blood pressure.

In this video we are going to know about the circulatory system, come with us to this adventure and learn all you can. ▶SUBSCRIBE TO HAPPY LEARNING! http://bit.ly/HappyLearningTV ▶Web site: https://happylearning.tv/en/ ▶Follow us on Facebook: https://www.facebook.com/HappyLearningTv Recommended video: The Elephant https://www.youtube.com/watch?v=qZrXD... The main function of the circulatory system is to carry, through the blood, the nutrients to the cells of our body. It is formed by the heart, arteries and veins and its proper functioning is essential for us to have good health. I have a curiosity Do you know how much all the artery and veins would measure together, put in single file? They would measure 97,000 kilometres, which would be equivalent to almost two and a half laps to Earth, it's incredible, right? The heart has the main role in making sure that the blood travels around the body. With its one hundred thousand pulsations per day it ensures that blood circulates throughout our body allowing it to distribute oxygen and nutrients into our cells. We are going to start a journey through the circulatory system so we can understand it much better. The journey of blood begins in the heart. With the pulsations of the heart the blood comes out through one of the great highways of the circulatory system called the Aorta. From that moment, the blood flows through our body through many veins. It reaches the neck, head and brain through one side. From there, the blood continues to flow into our arms then through the aorta, around the thorax and abdomen and finally reaching both of our legs. During this trip, the blood is delivering oxygen and nutrients to the cells through the capillary veins. As this trip is circular, that is to say it has no end, the blood starts the trip back to the heart to regain nutrients and oxygen.

Capillaries - What Are Capillaries - Functions Of Capillaries
 
00:34
In this video I discuss the functions of capillaries, and what do capillaries do in the cardiovascular system. Transcript What are capillaries? Capillaries are small blood vessels that are part of the circulatory system. They connect arteries and veins, and many enter tissue forming a capillary bed. In this area, oxygen and other nutrients are released and carbon dioxide and other waste products are passed into the blood, which then enters veins. Capillaries are so small that only one red blood cell can pass through at a time. They are made up of a single layer of curved cells that have tiny gaps between them to allow substances to move in and out of the blood.

Cardiovascular disorders explained in terms or altered physiology. Physiology is vital to give us an understanding of the normal functioning of the body. This knowledge can help us to maintain health in the people we live and work with. Sometimes however, as a result of trauma, disease or degeneration, the body fails to function normally. This means that, by definition, the function has become abnormal. Abnormal body function is termed pathophysiology. An understanding of normal and abnormal body function is necessary if we are to understand what treatments are indicated in a particular situation. This means physiology, pathophysiology and patient management all interlink. Theory will then inform, and provide rationales for interventions. The focus of this video is abnormal function, but this must be considered in the context of physiology and clinical practice. If we understand this linking and interdependence, we can use our knowledge of theory and practice to directly benefit patient care.

View full lesson: http://ed.ted.com/lessons/how-the-heart-actually-pumps-blood-edmond-hui For most of history, scientists weren't quite sure why our hearts were beating or even what purpose they served. Eventually, we realized that these thumping organs serve the vital task of pumping clean blood throughout the body. But how? Edmond Hui investigates how it all works by taking a closer look at the heart's highly efficient ventricle system. Lesson by Edmond Hui, animation by Anton Bogaty.

The Circulatory System : Function and Definition of Arteries
 
07:02
The Circulatory System Function and Definition of Arteries Arteries are blood vessels which carry blood away from the heart. All of which, with the exception of the pulmonary artery, carry oxygenated blood. The most widely known artery within the human body is the Aorta. This is the largest of all blood vessels and transports blood away from the left ventricle of the heart where it then branches into smaller arteries. As the arteries devide further they become smaller and smaller, until they are classed as arterioles. Arterioles continue to branch into smaller and smaller vessels which, once they have decreased in size below 10 micrometers in diameter are known as capillaries.

Blood Vessels In The Body - What Are Blood Vessels - Functions Of Blood Vessels
 
00:44
In this video I discuss what are blood vessels, the functions of blood vessels in the body, and what do blood vessels do. Transcript What are blood vessels? Blood vessels are part of the circulatory system, and they transport blood throughout the body. Blood vessels consist of arteries, arterioles, capillaries, venules and veins. How they work… Arteries carry oxygen rich blood away from the heart and eventually merge into smaller vessels called arterioles. The arterioles connect to capillaries where oxygen and other nutrients pass from the blood into tissues and organs. The tissues pass carbon dioxide and other waste products into the blood here as well. This deoxygenated Blood then flows from the capillaries into venules. The venules then merge into veins, which carries the blood back to the heart. Other sources... https://www.fi.edu/heart/blood-vessels
