it is where your blood goes through your body! it has veins. it goes from one place to another. ( the blood)
The respiratory system transfers oxygen from the lungs to the circulatory system. The circulatory system transfers the carbon dioxide into your lungs and we then breathe it out.

The circulatory system is vital for life.
what kind of cell is the epithelial cell
Muscular Circulartory Nervous Digestive im so smart!:)
yes
Because it helps to keep our blood and water balance in our body
there are alot of ways but it is because we have more technoligy in these days
Without the circulatory system, there is no way for the nutrients we digest to get to all the tissues they need to go. Oxygen wouldn't be able to get there either and the cells would die.
