Each of the actual valves has it s own specific name though. Tricuspid valve is the one located at the entrance of the right ventricle. It prevents the blood from washing back into the right atrium. It gets its name from the three cusps or flaps that make up the valve. Pulmonary semilunar valve is located between the right ventricle and the pulmonary artery.
Mitral valve is made of very heavy cusps and is located at the entrance of the left ventricle.
This is a powerful valve that closes as the left ventricle begins each of its contractions to ensure the oxygenated blood doesn t re-enter the left atrium. Aortic valve is located, as its name would imply, between the left ventricle s exit and the aorta itself. Even though the heart is split up into two distinct halves, these two must work together to function properly. As the upper chamber finishes its squeeze, the lower chamber begins its work. As the walls of the atrium complete their contraction, the ventricle begins its active stage.
