The heart pumps the "fresh"  blood through the arteries, which carries food, and oxygen through the body, and then the blood goes into the capillaries and goes into the veins when it picks up carbon dioxide and gets returned to the heart where the blood gets renewed and the process repeats.

Extra information: The carbon dioxide gets expelled by the lungs.
