Question

Quizplus · Accepted Answer

The smooth muscle is not directly involved in preventing abnormal clotting in blood vessels. The smooth endothelium, heparin produced by basophils, and antithrombin produced by the liver all play roles in preventing blood clots, whereas the smooth muscle's primary function is related to vessel constriction and dilation, not directly preventing clotting.
