Question

question 25
which of the following statements regarding hemostasis is false?
a platelets release thromboplastin.
b thromboplastin reacts with prothrombin to form thrombin.
c thrombin works to convert fibrinogen to fibrin.
d fibrin converts platelets into a clot.

Explanation:

In the process of hemostasis, damaged tissue (not platelets) releases thromboplastin. Thromboplastin reacts with prothrombin to form thrombin. Thrombin converts fibrinogen to fibrin. Fibrin forms a mesh - like structure that traps platelets to form a clot, not that fibrin converts platelets into a clot.

Answer:

A. Platelets release thromboplastin., D. Fibrin converts platelets into a clot.
