Detailed explanation-1: -Your pulmonary valve manages blood flow from your heart’s right ventricle to your pulmonary trunk . Its main function is to help oxygen-poor blood reach your lungs, where it gains oxygen and gets rid of carbon dioxide.
Detailed explanation-2: -The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
Detailed explanation-3: -The pulmonary artery then carries the oxygen-poor blood from your heart to the lungs. Your lungs add oxygen to your blood. The oxygen-rich blood returns to your heart through the pulmonary veins.
Detailed explanation-4: -The heart consists of four chambers, two atria (upper chambers) and two ventricles (lower chambers). There is a valve through which blood passes before leaving each chamber of the heart. The valves prevent the backward flow of blood.
