Question

The function of the lining of an artery is to:
A)help maintain BP by raising it
B)prevent abnormal clotting
C)help maintain BP by lowering it
D)keep the blood moving

Accepted Answer

The lining of an artery, also known as the endothelium, plays a critical role in preventing abnormal blood clotting by producing compounds that prevent platelets from aggregating and promoting anticoagulation. The other options are incorrect as the lining of an artery does not actively raise or lower blood pressure, but rather maintains it within a normal range, and its primary function is not to keep the blood moving, but to facilitate proper blood flow.
