Blood Vessels: transport blood throughout the body, and there are 3 different types.
*Arteries: which carry blood away from the heart
*Capillaries: which enable the exchange of water and chemicals between the blood and tissues
*Veins: which carries blood from the capillaries back towards the heart.
Blood: is a specialized fluid that provides the body with nutrients and the oxygen it needs to survive.
