oxygen-bearing blood to all the tissues of the body. When the heart contracts it pushes the blood
out into two major loops or cycles. In the systemic loop, the blood circulates into the body’s
systems, bringing oxygen to all its organs, structures and tissues and collecting carbon dioxide
waste. In the pulmonary loop, the blood circulates to and from the lungs, to release the carbon
dioxide and pick up new oxygen. The systemic cycle is controlled by the left side of the heart,
the pulmonary cycle by the right side of the heart. Let’s look at what happens during each cycle:

The systemic loop begins when the oxygen-rich blood coming from the lungs enters the
upper left chamber of the heart, the left atrium. As the chamber fills, it presses open the mitral
valve and the blood flows down into the left ventricle. When the ventricles contract during a
heartbeat, the blood on the left side is forced into the aorta. This largest artery of the body is an
inch wide. The blood leaving the aorta brings oxygen to all the body’s ce...
