Anatomy Of The Heart And Blood Flow

The size of your heart can vary depending on your age size and the condition of your heart. Your heart is located under your ribcage in the center of your chest between your right and left lungs.

There are six structures on each of these sides that are used during blood.

Anatomy of the heart and blood flow. The heart is the fluid pump of the cardiovascular system. Anatomy of the heart. The left side and the right side.

Blood is prevented from clotting in the blood vessels by their smoothness and the finely tuned balance of clotting factors. Its muscular walls beat or contract pumping blood to all parts of your body. This is the process called oxygenation.

When learning the blood flow of the heart it helps to divide it up into two sections. The heart valves work the same way as one way valves in the plumbing of your home. The aortic and pulmonic valves lie between the ventricles and the major blood vessels leaving the heart.

And it pumps blood to the lungs where it receives oxygen after the body has used it up. The flow of blood through the heart is controlled by the opening and closing of valves and the contraction and relaxation of the myocardium. Its included in this module as one of the steps in the heartbeat cycle.

Blood now moves from the right ventricle through the pulmonary semilunar valve which is the valve that separates the right ventricle and the lungs. They prevent blood from flowing in the wrong direction. As we previously learned this is called the pulmonary circuit.

Blood is conducted through blood vessels arteries and veins. Each valve has a set of flaps called leaflets or cusps. It pumps blood and nutrients to all of the organs of the body.

The chambers of the heart are shown including the right atrium left atrium right ventricle and left ventricle. In the lungs the blood picks up oxygen and drops off carbon dioxide before returning to the heart. Heart valves are controlled by pressure changes within each chamber and contraction and relaxation are controlled by the hearts conduction system.

Blood enters the heart through two large veins the inferior and superior vena cava emptying oxygen poor blood from the body into the right atrium of the heart. However the blood flow through the heart is a little different. Right side of the heart.

The valves are also shown including the tricuspid bicuspid mitral aortic and.
