hemosztázis
Hemostasis refers to the physiological process that stops bleeding. It is a complex and tightly regulated cascade involving blood vessels, platelets, and coagulation factors. When a blood vessel is injured, the first response is vasoconstriction, narrowing the vessel to reduce blood flow. This is followed by platelet activation and aggregation, forming a temporary plug at the site of injury.
The coagulation cascade then kicks in, a series of enzymatic reactions involving numerous clotting factors. This
Once the vessel wall has healed, the clot is broken down through a process called fibrinolysis. This
