The circulatory system is located everywhere because the circulatory system is how blood is pumped through your veins, and your veins are everywhere.

The heart is a major function because it controls the blood flow. The heart pumps the blood through the body and that’s where the blood returns.

The circulatory system works with the excretory system because the blood carries carbon dioxide from the cells to the heart which it goes up to the lungs. It also carries other waste products to the liver or kidneys. If your system does not carry the waste you might have a stomach ache.
