Question

Which of the following must occur first during hemostasis?

1) Clot retraction
2) Formation of thrombin
3) Thrombolysis
4) Formation of fibrin

Answer 1

Clot retraction must occur first during hemostasis.

Step-by-step explanation:

The correct answer is (1) Clot retraction. During hemostasis, clot retraction is the first step to occur. This process involves the pulling together of the edges of the clot, effectively shrinking it in size and reinforcing the strength of the clot. Clot retraction is mainly mediated by platelets.
