The circulatory system circulates blood around the body. The blood passes through the lungs, where it loses carbon dioxide and gains oxygen. All cells need oxygen to function and carbon dioxide is a form of waste produced in the cells. The digestive system breaks down food and absorbs.
In the circulatory system there is the distribution of oxygen to the body and in the respiratory system the gas exchange.
