ANATOMY

Detailed explanation-1: -Your tricuspid valve opens to let blood travel from your right atrium to your right ventricle. When your right ventricle is full it squeezes, which closes your tricuspid valve and opens your pulmonary valve. Blood flows through your pulmonary artery to your lungs, where it gets oxygen.

Detailed explanation-2: -Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.

Detailed explanation-3: -Adding oxygen to blood 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-4: -The arteries of the pulmonary circuit carry deoxygenated blood, whereas the arteries of the systemic circuit carry oxygenated blood. The right side of the heart is the pulmonary circuit pump, and the left side of the heart is the systemic circuit pump.

Detailed explanation-5: -De-oxygenated blood leaves the heart, goes to the lungs, and then enters back into the heart. De-oxygenated blood leaves through the right ventricle through the pulmonary artery. From the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve) into the right ventricle.
