Cells use the circulatory system to help get rid of wastes. Diffusion occurs at the tissues, allowing for nutrients and oxygen to enter the cells, and for carbon dioxide and other wastes to be removes from the cells.The excretory system is a close partner with the circulatory system because they both remove wastes from the body. The excretory system removes excess, unnecessary materials from the body(as opposed to individual cells) so as to help maintain homeostasis within the body. It is responsible for the elimination of the waste products of metabolism as well as other liquid and wastes, such as urine and feces.So to simplify, individual cells use the circulatory system to remove wastes, while the excretory system removes wastes from the circulatory system.
