Heparin is a molecule that acts as an anticoagulating agent on a blood protein. It is naturally synthesized by the body, specifically the immune system, and can also be supplied through pork or beef offal. Heparin is administered in cases of thrombosis, a blockage of a blood cell
, in order to liquefy a clot. In cases with coagulating disorder, or conditions such as hemophilia
, heparin can be lethal as it causes severe hemorrhage.
