What is the structure and the function of the parts of the Circulatory System and how do they interact?
The circulatory system contains one very important cardiac muscle. We call this muscle the heart. Understanding the heart is very important to the circulatory system. The heart contains four different chambers. The chambers are called the Right Atrium, Left Atrium, Right ventricle, and the Left Ventricle. Blood that has been taken of its oxygen flows through and out of the capillaries into a vein. Veins are a type of blood vessel. They deliver blood towards the heart. Veins are a structure that are like tubes. Similar to Veins are Arteries. Arteries carry blood away from the heart. Many Veins merge again and again until the form a Superior and inferior Vena Cava. The Vena Cava is a vein that enters the heart. The Superior Vena Cava enters the heart through the top, while the Inferior Vena Cava enters the heart through the bottom. The Vena Cava leads towards the Right Atrium of the heart. The Right Atrium holds blood that is to be taken into the Right ventricle. The blood then travels through a one way valve that lets blood into the ventricle, but not out. Through the valve is the right ventricle, it contains muscle tissue that squeezes to push blood toward the other end of the ventricle. Once squeezed, the blood passes through another valve to the Pulmonary Artery. The Pulmonary Artery delivers blood to capillaries in the lungs, where gas exchange happens and oxygen in the lungs is traded for carbon dioxide in the blood. Now the blood is rich in Oxygen. The blood then goes down the Pulmonary vein to the Left Atrium of the heart. The blood passes through another valve and goes into the Left ventricle to be squeezed back into the body. On it's way out of the Left ventricle, blood passes through another valve. The blood then goes out the Aorta, a big Artery that is similar to the Vena Cava, and to the body and the whole process is repeated.
This picture shows the Circulatory system and the oxygen rich and oxygen poor veins.
