Your heart is a pump. It s a muscular organ about the size of your fist, situated slightly left of center in your chest. Your heart is divided into the right and the left side. The division protects oxygen rich blood from mixing with oxygen poor blood. Oxygen poor blood returns to the heart after circulating through your body.
The right side of the heart, comprising the right atrium and ventricle, collects and pumps blood to the lungs through the pulmonary arteries.
The lungs refresh the blood with a new supply of oxygen. The lungs also breathe out carbon dioxide, a waste product.
Oxygen rich blood then enters the left side of the heart, comprising the left atrium and ventricle.
The left side of the heart pumps blood through the aorta to supply tissues throughout the body with oxygen and nutrients.
