Anatomy Of The Heart And Blood Flow

The valves are also shown including the tricuspid bicuspid mitral aortic and. However the blood flow through the heart is a little different.

Blood Flow Of The Heart

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.

Anatomy of the heart and blood flow. This is the process called oxygenation. Blood is conducted through blood vessels arteries and veins. 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. The size of your heart can vary depending on your age size and the condition of your heart. Right side of the heart.

Its muscular walls beat or contract pumping blood to all parts of your body. And it pumps blood to the lungs where it receives oxygen after the body has used it up. Blood is prevented from clotting in the blood vessels by their smoothness and the finely tuned balance of clotting factors.

It pumps blood and nutrients to all of the organs of the body. Heart valves are controlled by pressure changes within each chamber and contraction and relaxation are controlled by the hearts conduction system. The left side and the right side.

Your heart is located under your ribcage in the center of your chest between your right and left lungs. They prevent blood from flowing in the wrong direction. Each valve has a set of flaps called leaflets or cusps.

When learning the blood flow of the heart it helps to divide it up into two sections. The heart is the fluid pump of the cardiovascular system. Blood now moves from the right ventricle through the pulmonary semilunar valve which is the valve that separates the right ventricle and the lungs.

The aortic and pulmonic valves lie between the ventricles and the major blood vessels leaving the heart. In the lungs the blood picks up oxygen and drops off carbon dioxide before returning to the heart. The heart valves work the same way as one way valves in the plumbing of your home.

As we previously learned this is called the pulmonary circuit. There are six structures on each of these sides that are used during blood. The chambers of the heart are shown including the right atrium left atrium right ventricle and left ventricle.
