Click through this slideshow to learn about the heart.
When blood circulates in the body, it enters the heart through the right atrium, passes through to the right ventricle, and flows out through the pulmonary artery to the lungs, where it picks up oxygen and gets rid of carbon dioxide.
From the lungs, blood returns to the left atrium and then enters the left ventricle, where it is pumped to the body through the aorta.
