Coagulation:In medical terms, coagulation refers to the process of blood clotting, where blood transforms into solid clumps or clots. Over 30 different types of cells and substances in the blood influence this process. It begins with blood platelets, which release a substance that interacts with calcium ions in the blood to create thromboplastin. This, in turn, triggers a complex series of reactions that convert a specific protein into thrombin. Thrombin, an enzyme that breaks down proteins, changes fibrinogen, a protein, into fibrin. Fibrin is an insoluble protein that forms a complex network of tiny threadlike structures known as fibrils, causing the blood plasma to solidify. Within this fibril network, blood cells and plasma become trapped, resulting in a clot.Tissues can also undergo coagulation through various methods such as electrocoagulation, laser coagulation, or photocoagulation.
