Detailed explanation-1: -The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart. From there, the blood flows through the tricuspid valve (TV) into the right ventricle (RV), or the right lower chamber of the heart.
Detailed explanation-2: -Your pulmonary arteries carry blood from your heart to your lungs. They’re the only arteries in your body that carry oxygen-poor (deoxygenated) blood. Your main pulmonary artery (pulmonary trunk) leaves your right ventricle at your pulmonary valve.
Detailed explanation-3: -The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.
