PATHOLOGY

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 right and left ventricles-pump blood out of your heart.

Detailed explanation-2: -The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle).

Detailed explanation-3: -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-4: -The heart has 4 chambers, 2 upper chambers (atria) and 2 lower chambers (ventricles). Blood passes through a valve before leaving each chamber of the heart. The valves prevent the backward flow of blood.
