The human heart has four chambers, which are the left and right atria and the left and right ventricles. Blood enters the right atrium where it then passes through the right ventricle.
The right ventricle pumps the blood back to the lungs where it is oxygenated and sent to the left atrium. From there it heads over to the left ventricle. The left ventricle is responsible for sending the blood to the aorta, which then sends oxygenated blood throughout the entire body.
With each pump of the heart, between 60 and 70 milliliters of blood are sent throughout the body. This equals around four to five liters per minute.
