Answer:
The human heart is about the size of a human fist and is divided into four chambers, namely two ventricles and two atria.
The ventricles are the chambers that pump blood and atrium are the chambers that receive blood. Among which both right atrium and ventricle make up the “right heart,” and the left atrium and ventricle make up the “left heart.” The structure of the heart also houses the biggest atrium from the lungs via the pulmonary veins. Read on to explore more about the structure of the heart.
The right ventricle pumps the blood to the lungs for re-oxygenation through the pulmonary arteries. The right semilunar valves close and prevent the blood from flowing back into the heart. Then, the oxygenated blood is received by the left atrium from the lungs via the pulmonary veins.
