Functions
Maintaining Body TissueThe circulatory system plays a big role in maintaining body tissue. This happens by supplying food that is carried through blood to the tissue and carrying waste away.

RespirationThe circulatory system also helps the body breathe. It can do this by bringing carbon dioxide to the heart through blood. The heart then pumps the carbon dioxide to the lungs where the lungs turn it into oxygen. The now blood rich with oxygen gets pumped around the body.

NutritionThe body also needs the help of the circulatory system for nutrition. The circulatory system is able to do this by carrying the digested food particles around the body with the blood stream.
