Answer 2

The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries. Blood vessels flow bloodthroughout the body. Arteries transportblood 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

The blood vessels are the components of the circulatory system that transport bloodthroughout the human body. These vessels transport blood cells, nutrients, and oxygen to the tissues of the body. They also take waste and carbon dioxide away from the tissues. Blood vessels are needed to sustain life, because all of the body's tissues rely on their functionality.
