blood vessels
Blood vessels are any of the tubes through which blood flows through the body.
Veins carry the blood throughout the body. It's Where The Blood Travels Through.
Oxygen is breathed through the nose or mouth and travels to the lungs through the bronchial tubes, then absorbed through the alveoli into the bloodstream. In the bloodstream the oxygen is transported all over the body by red blood cells. So, red blood cells would be your answer.
the circulatory system
circulation
Tubes that carry blood are collectively known as blood vessels. These include veins, arteries, and capillaries.
Carbon dioxide leaves the blood and travels through the lungs before leaving your body.
the heart pumps the blood to different part of the body
