The brain checks up on the amount of carbon dioxide in the blood and adjusts the rate of breathing. The brain “communicates” with the lungs using nerves from the brain to lungs.

Blood vessels carry nutrients (like glucose) and oxygen to the muscle cells that need them. Blood vessels take away carbon dioxide and waste from muscle cells.

Blood vessels deliver nutrients and oxygen for all the intestinal cells to function. Blood in blood vessels picks up nutrients absorbed by the intestines and carries them away to other parts of the body that need them.

Nerves send messages to muscles to tell them how and where to move. Nerves check up on the body’s need for oxygen in the muscles and adjust breathing rate and heart rate as needed.
