Explanation:
The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries. Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances.
