Following a deep cut, which mechanism explains why blood at the wound site eventually forms a stable clot, halting the bleeding?

A)Reduced vessel wall vasoconstriction
B)Inhibition of platelet degranulation
C)Activation of the coagulation cascade
D)Increased red blood cell rigidity

💡 Explanation

The coagulation cascade is a series of enzymatic reactions that amplify to form fibrin, stabilizing the platelet plug and forming a clot; because the cascade activates clotting factors, a stable clot forms. Therefore, the answer is activation of the coagulation cascade rather than vasoconstriction, platelet inhibition, or RBC rigidity, which don't fully explain the process.
