As your heart muscle contracts, it pushes blood through your heart. Your heart pumps blood from its left side, through the aorta (the main artery leaving the heart) and into the arteries. The blood travels through your arteries, which divide off into smaller and smaller blood vessels called capillaries.

Answer:
The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs.
