To determine which blood vessels carry blood away from the heart, we need to know the main types of blood vessels and their functions.
1. Arteries: Arteries are blood vessels that carry oxygenated blood away from the heart to various parts of the body. They have thick muscular walls which help in maintaining blood pressure and facilitating the flow of blood.
2. Capillaries: Capillaries are the narrowest blood vessels in our body. They connect the smallest arteries, called arterioles, to the smallest veins, called venules. Capillaries serve as the site of exchange of nutrients, oxygen, and waste products between the blood and surrounding tissues.
3. Veins: Veins are blood vessels that carry deoxygenated blood back to the heart from the various parts of the body. Unlike arteries, veins have thinner walls and contain valves to prevent the backflow of blood. They rely on the contraction of muscles and the action of one-way valves to help propel blood back to the heart.
Based on this information, we can conclude that the blood vessels that carry blood away from the heart are arteries.
