ANATOMY

Detailed explanation-1: -The pulmonary valve prevents blood from going backward from the pulmonary artery to the right ventricle.

Detailed explanation-2: -The pulmonary valve prevents the backflow of deoxygenated blood from the pulmonary artery into the right ventricle while the aortic valve prevents the backflow from aorta into the left ventricle.

Detailed explanation-3: -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-4: -Your main pulmonary artery and your aorta are the two great vessels that carry blood out of your heart. A crucial difference is that your pulmonary artery carries oxygen-poor (deoxygenated) blood, while your aorta carries oxygen-rich (oxygenated) blood.

Detailed explanation-5: -The pulmonary valve controls blood flow from the right ventricle into the pulmonary arteries, which carry blood to your lungs to pick up oxygen.
