The stoppage of bleeding is called which of the following?

• A. Coagulation
• B. Hemostasis
• C. Thrombosis
• D. Atherosclerosis

Answer: (B)

The stoppage of bleeding is hemostasis. This is a coordinated response to vessel injury that slows blood flow, forms a temporary platelet plug, and then reinforces it with a fibrin clot to create a stable seal. Vascular spasm reduces blood loss, platelets adhere and aggregate to form a plug, and the coagulation cascade solidifies the plug with fibrin. Coagulation is the chemical part of this process, but hemostasis covers the whole sequence from initial constriction to final clot formation and repair. Thrombosis would be an abnormal clot forming inside a vessel, which can cause blockage. Atherosclerosis is the buildup of plaques in arteries, not the immediate stopping of bleeding.
