ANATOMY

Detailed explanation-1: -The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs.

Detailed explanation-2: -The pulmonary circulation is a short loop from the heart to the lungs and back again. The systemic circulation carries blood from the heart to all the other parts of the body and back again.

Detailed explanation-3: -The right ventricle (RV) pumps oxygen-poor blood through the pulmonary valve (PV) into the main pulmonary artery (MPA). From there, the blood flows through the right and left pulmonary arteries into the lungs.

Detailed explanation-4: -The blood enters the heart’s right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs. The pulmonary artery then carries the oxygen-poor blood from your heart to the lungs. Your lungs add oxygen to your blood.

Detailed explanation-5: -pulmonary vein: The vein that returns blood to the left atrium of the heart after it has circulated through the lungs. pulmonary artery: The artery that connects the right ventricle of the heart to the lungs.
