Circulatory System. The circulatory system includes the heart, blood, and a huge network of blood vessels that carry blood all over the body. The job of the circulatory system is to deliver oxygen to cells all over the body and then to carry out waste product like carbon dioxide. The heart is an organ made out of muscle. Itâs job is to pump blood through the body.
But it also removes a waste, carbon dioxide. Another system in your body, the excretory system, also removes wastes. The excretory system moves waste from your digestive system and from your blood out of your body.
