| veins | re an important part of our circulatory system. They are responsible for returning deoxygenated blood back to the heart after arteries carry blood out. |
| capillaries | Capillaries form a network throughout the body for the exchange of oxygen, metabolic waste products, and carbon dioxide between blood and tissue cells. |
| arteries | A vessel that carries blood high in oxygen content away from the heart to the farthest reaches of the body. |
| oxygenated | To combine or mix with oxygen, as in a physical, chemical, or biological system. Blood is oxygenated in the lungs |
| deoxygenated | is when oxygen has been removed from blood or water. |
