Once a clot has formed in a ruptured vessel, the area to be repaired is made smaller by:
A)more clotting
B)clot retraction
C)heparin
D)hemolysis

Question

Quizplus · Accepted Answer

Clot retraction occurs when platelets in the clot contract, pulling the edges of the ruptured vessel closer together and making the area to be repaired smaller. This is different from more clotting (choice A), which would actually make the clot bigger and potentially obstruct blood flow.
