ANATOMY

Detailed explanation-1: -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-2: -The pulmonary valve normally acts like a one-way door from your heart’s right ventricle to the lungs. Blood flows from the right ventricle through the pulmonary valve to the pulmonary artery and then into the lungs, where it picks up oxygen to deliver to your body.

Detailed explanation-3: -In normal conditions, the pulmonic valve prevents regurgitation of deoxygenated blood from the pulmonary artery back to the right ventricle. It is a semilunar valve with 3 cusps, and it is located anterior, superior, and slightly to the left of the aortic valve.

Detailed explanation-4: -Valves maintain direction of blood flow The pulmonary valve is between the right ventricle and the pulmonary artery. The mitral valve is between the left atrium and left ventricle. The aortic valve is between the left ventricle and the aorta.
