What vessels carry blood away from the heart to the body?

Explanation:
The key idea is the direction of blood flow in the vessels: arteries carry blood away from the heart, veins carry blood back toward the heart, and capillaries are the tiny vessels where exchange with tissues happens. Arteries are the vessels that move blood outward from the heart to the body's tissues. In systemic circulation, the left ventricle pumps into the aorta and its branches to deliver oxygen-rich blood to all organs. The term “arteries” covers all vessels carrying blood away from the heart, not just a single vessel. A helpful nuance is that the pulmonary artery also carries blood away from the heart, but it sends blood to the lungs and is part of a special circuit.
