Best Answer

The heart is a muscular organ which drives oxygenated blood around the whole body through the blood vessels.

The right half pumps blood to the lungs through the pulmonary arteries. When it returns to the left side of the heart, it is pumped into the aorta, which is the large artery connected to arteries throughout the body.
