Cardio vascular system

Capillaries carry blood very close to the cells of the tissues of the body in order to exchange gases, nutrients, and waste products.

Birds, mammals, and crocodilians show complete separation of the heart into two pumps, for a total of four heart chambers; it is thought that the four-chambered heart of birds and crocodilians evolved independently from that of mammals. Paul's site is loaded with many more articles, and worth scouring.

Circulatory system

In the systemic circulation, arteries always carry oxygenated blood and veins always carry oxygen-poor blood. Cardiovascular System Physiology Functions of the Cardiovascular System The cardiovascular system has three major functions: Heart is the main organ of cardiovascular system and it is responsible for distributing blood all over human body.

It also makes it more likely that blood clots will form and partially or completely block blood flow. AV valves - open when pressure in the atria is greater than pressure in the ventricles i.

The flaps are thus pushed upward until they meet and unite, forming a complete partition between the atria and the ventricles. They're also high in protein and provide a good source of fiber.

Buy pre-cut fruits and vegetables if you're looking to save time and use them to make healthy snacks and build nutritious plates.

The platelet plug will serve as a temporary seal to keep blood in the vessel and foreign material out of the vessel until the cells of the blood vessel can repair the damage to the vessel wall.

It sends out an electrical signal to start the contracting pumping of the heart muscle. The left side of the heart receives oxygenated blood from the lungs and pumps it through the systemic arteries to the tissues of the body. If the flow of blood is stopped, life will stop. When the pressure in the cuff falls below systolic pressure, blood can again entery the artery.

The number at this point indicates the diastolic pressure. Even though the two openings do not quite coincide in position, blood still passes through, from the right atrium to the left.

The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.

Human cardiovascular system - Origin and development: In the embryo, formation of the heart begins in the pharyngeal, or throat, region. The first visible indication of the embryonic heart occurs in the undifferentiated mesoderm, the middle of the three primary layers in the embryo, as a thickening of invading cells.
