which parts of the heart receive blood from the rest of the body
The right side of the heart collects oxygen-depleted blood and pumps it to the lungs, through the pulmonary arteries, so that the lungs can refresh the blood with a fresh supply of oxygen. The left side of the heart receives oxygen-rich blood from the lungs, then pumps blood out to the rest of the body's tissues, through the aorta. Valves Maintain Direction of Blood Flow As the heart pumps blood, a series of valves open and close tightly.
