ANATOMY

Detailed explanation-1: -The pulmonary valve prevents blood from going backward from the pulmonary artery to the right ventricle. Mitral valve: This valve has two leaflets. They allow blood to flow from the lungs into the left atrium. And they prevent backward flow from the left ventricle to the left atrium.

Detailed explanation-2: -Pulmonary Valve (or Pulmonic Valve) Separates the right ventricle from the pulmonary artery. Opens to allow blood to be pumped from the right ventricle to the lungs (through the pulmonary artery) where it will receive oxygen. Prevents the back flow of blood from the pulmonary artery to the right ventricle.

Detailed explanation-3: -The semilunar valves are located at the connections between the pulmonary artery and the right ventricle, and the aorta and the left ventricle. These valves allow blood to be pumped forward into the arteries, but prevent backflow of blood from the arteries into the ventricles.

Detailed explanation-4: -The pulmonary valve or pulmonic valve (PV) is one of the four cardiac valves. It is the semilunar valve that allows blood to exit the right ventricle (RV). It opens during systole and closes during diastole.

Detailed explanation-5: -The semilunar valves permit blood to flow into the arteries from the ventricles and prevent the backward flow of blood from the arteries into the ventricles.
