ANATOMY

Detailed explanation-1: -A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings.

Detailed explanation-2: -A typical heart has two upper and two lower chambers. The upper chambers-the right and left atria-receive incoming blood. The lower chambers-the right and left ventricles-pump blood out of your heart.

Detailed explanation-3: -There are two atria (upper chambers) called your right atrium and left atrium. In addition, there are two ventricles (lower chambers) called your right ventricle and left ventricle. Each chamber plays an important role in your heart’s functioning.

Detailed explanation-4: -The heart has four chambers: two atria and two ventricles. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.

Detailed explanation-5: -The right atrium pumps the blood to the right ventricle. The right ventricle pumps the low-oxygen blood to the lungs to pick up a fresh supply of oxygen. The left atrium receives to high-oxygen blood from the lungs and pumps it to the left ventricle.
