Detailed explanation-1: -Blood vessels are the network of tubes through which blood is pumped around the body. Along with the heart and the blood, the blood vessels form the cardiovascular system. The 3 main types of blood vessels are: arteries-these carry blood pumped away from the heart; they are the largest and strongest blood vessels.

Detailed explanation-2: -A blood vessel is a tube that carries blood. Oxygen rich blood leaves the left side of the heart and enters the aorta. The aorta branches into arteries, which eventually branch into smaller arterioles. Arterioles carry blood and oxygen into the smallest blood vessels, the capillaries.

Detailed explanation-3: -There are three types of blood vessels: Arteries carry blood away from your heart. Veins carry blood back toward your heart. Capillaries, the smallest blood vessels, connect arteries and veins.

Detailed explanation-4: -Oxygenated blood from the lungs is transported to the left side of the heart into the aorta, then to arteries, arterioles, and finally capillaries where the exchange of nutrients occurs. Loading and unloading of oxygen and nutrients occur mostly in the capillaries.

Detailed explanation-5: -blood vessels: Blood moves through many tubes called arteries and veins, which together are called blood vessels. The blood vessels that carry blood away from the heart are called arteries. The ones that carry blood back to the heart are called veins.
