Detailed explanation-1: -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.
Detailed explanation-2: -atrium, in vertebrates and the higher invertebrates, heart chamber that receives blood into the heart and drives it into a ventricle, or chamber, for pumping blood away from the heart.
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.
