Clot formation involves a complex cascade of events called the coagulation cascade. This process can be divided into three main stages: vasoconstriction, platelet plug formation, and coagulation.
1. Vasoconstriction: When a blood vessel is injured, it constricts to reduce blood flow. 2. Platelet Plug Formation: Platelets adhere to the site of injury and release chemicals that attract more platelets, forming a temporary plug. 3. Coagulation: This involves a series of enzymatic reactions that lead to the formation of fibrin, which stabilizes the platelet plug into a more permanent clot.
