Detailed explanation-1: -The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated.
Detailed explanation-2: -Different types of hearts have different numbers of these chambers: two-chambered hearts have one ventricle and one atrium. three-chambered hearts have one ventricle and two atria. four-chambered hearts have two ventricles and two atria.
Detailed explanation-3: -The four-chambered heart provides an efficient solution by keeping oxygenated and non-oxygenated blood separate. The supply of oxygen to the body can also be improved by increasing how often the heart contracts.
Detailed explanation-4: -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.
