What in your body stops bleeding?

The body stops bleeding primarily through a process called hemostasis, which involves three key steps: vascular spasm, platelet plug formation, and coagulation. When a blood vessel is injured, it constricts to reduce blood flow. Platelets quickly gather at the injury site, adhering to the damaged area and forming a temporary plug. Subsequently, a series of biochemical reactions leads to the formation of a fibrin clot, which stabilizes the plug and prevents further bleeding.
