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 Capillaries. The blood capillaries are where the important functions of the circulation take place: the exchange of material between circulation and cells. Capillaries are the smallest of the body's blood vessels. They are only one cell thick, and they are the sites of the transfer of oxygen and other nutrients from the bloodstream to other tissues in the body; they also collect carbon dioxide waste materials and fluids for return to the veins.
