Which valves are tricuspid

When the left ventricle contracts, it moves blood through the aortic valve into the aorta. The aorta then provides blood to the rest of the body. The job of the valves is to move the blood through the heart. When the two atrium chambers contract, the tricuspid and mitral valves open, which both allow blood to move to the ventricles. When the two ventricle chambers contract, they force the tricuspid and mitral valves to close as the pulmonary and aortic valves open.

The blood that is meant to leave the ventricles to travel to the body is supposed to be prevented from flowing in the wrong direction by the parts of the aortic and pulmonary valves called the cusps. The cusps help the valves create a tight seal, which helps blood flow in the correct direction. Most heart valve disease occurs in the valves on the left side of the heart — the aortic valve and the mitral valve. The heart consists of four chambers, two atria upper chambers and two ventricles lower chambers.

There is a valve through which blood passes before leaving each chamber of the heart. The valves prevent the backward flow of blood. These valves are actual flaps that are located on each end of the two ventricles lower chambers of the heart.

They act as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle. Normal valves have three flaps, except the mitral valve, which has two flaps. About half the people with Ebstein anomaly have an atrial septal defect.
