The main
function of the four-chambered human heart is to keep blood moving constantly through the body. The
upper chambers of the heart are the atria. The thicker, more muscular, lower two chambers are the
ventricles. Blood enters the heart through the atria and leaves the heart through the ventricles. The
right atrium receives oxygen-poor blood from the head and body through two large veins called the
venae cavae. The left atrium receives oxygen-rich blood from the lungs through pulmonary veins. After
they receive blood, the atria contract, pushing blood down into the ventricles. Then, both ventricles
contract. When the right ventricle contracts, it pushes the oxygen-poor blood from the right
ventricle out of the heart, toward the lungs, and through the pulmonary arteries. At the same time,
the left ventricle forcefully pushes oxygen-rich blood from the left ventricle out of the heart,
through the aorta, and to the arteries.
