Insulin lispro is a short-acting, man-made version of human insulin. Insulin lispro works by replacing the insulin that is normally produced by the body and by helping move sugar from the blood into other body tissues where it is used for energy.
The term circulation is most commonly associated with blood circulation in the body. Circulation is responsible for the action that moves nutrients, gases and wastes to and from cells, and helps stabilize body temperature and pH to maintain harmony. We cannot live without our blood circulating throughout our body.
Blood is circulated around the body through blood vessels by the pumping action of the heart. In animals with lungs, arterial blood carries oxygen from inhaled air to the tissues of the body, and venous blood carries carbon dioxide, a waste product of metabolism produced by cells, from the tissues to the lungs to be exhaled.
