Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It potentially results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair. The mechanism of coagulation involves activation, adhesion and aggregation of … Visa mer Platelet activation When the endothelium is damaged, the normally isolated underlying collagen is exposed to circulating platelets, which bind directly to collagen with collagen-specific Visa mer Numerous tests are used to assess the function of the coagulation system: • Common: aPTT, PT (also used to determine INR), fibrinogen testing (often by the Clauss method), platelet count, platelet function testing (often by PFA-100), thrombodynamics test Visa mer Procoagulants The use of adsorbent chemicals, such as zeolites, and other hemostatic agents are also used for sealing severe injuries quickly (such as in traumatic bleeding secondary to gunshot wounds).

WebbBlood Clots: Plugging the Breaks When an injury causes a blood vessel wall to break, platelets are activated. They change shape from round to spiny, stick to the broken vessel wall and each other, and begin to plug the break. They also interact with other blood proteins to form fibrin. WebbBlood clotting, also known as coagulation, is a complex process that occurs in the body to stop bleeding after an injury. The process involves a series of biochemical reactions that lead to the formation of a blood clot, which is a mass of blood cells and protein fibers that seals off a wound.
