Detailed explanation-1: -Your upper chambers are called your right atrium and left atrium. Your lower chambers are called your right ventricle and left ventricle. Your chambers work together to manage your heartbeat. They also send blood into your lungs to gain oxygen before recirculating throughout your body.

Detailed explanation-2: -The two atria are thin-walled chambers that receive blood from the veins. The two ventricles are thick-walled chambers that forcefully pump blood out of the heart.

Detailed explanation-3: -The top chambers of the heart are called the left atrium and right atrium. The bottom chambers of the heart are the left ventricle and right ventricle, which have thicker walls.

Detailed explanation-4: -Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.
