Detailed explanation-1: -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-2: -The right atrium receives blood from the body. This blood is low in oxygen. This is the blood from the veins. The right ventricle pumps the blood from the right atrium into the lungs to pick up oxygen and remove carbon dioxide.
Detailed explanation-3: -The heart has 4 main sections, or “chambers.” The top 2 chambers are called the right atrium and left atrium. The bottom 2 chambers are called the right and left ventricles. Each of these chambers has a valve that keeps blood flowing in 1 direction.
