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: -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: -Two chambered hearts are the heart which have one atrium and one ventricle to pump the blood. Complete answer: Fish have two chambered hearts, one atrium and one ventricle to pump the blood throughout the body. Atrium and ventricle are defined as true chambers whereas others are considered as accessory chambers.
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.
