PATHOLOGY

Detailed explanation-1: -Pulmonary valve: This valve also has three leaflets. They allow blood to pump from the right ventricle to the pulmonary artery. This artery leads to the lungs, where blood picks up oxygen. The pulmonary valve prevents blood from going backward from the pulmonary artery to the right ventricle.

Detailed explanation-2: -The pulmonary valve is one of four valves that control blood flow in the heart. It’s between the lower right heart chamber (right ventricle) and the artery that delivers blood to the lungs (pulmonary artery).

Detailed explanation-3: -The pulmonary valve usually acts like a one-way door from the lower right heart chamber to the lungs. Blood flows from the chamber through the pulmonary valve. It then goes to the pulmonary artery and into the lungs. Blood picks up oxygen in the lungs to take to the body.
