Which of the following is correct for extrinsic control of arteriolar radius?

Question

Quizplus · Accepted Answer

Extrinsic control of arteriolar radius refers to the regulation of blood vessel diameter by factors outside the vessel, such as nervous and hormonal signals. This control is important in the regulation of arterial blood pressure, as changes in arteriolar radius can affect the amount of blood flowing into a particular tissue or organ. Local adjustments, such as those due to changes in oxygen or metabolite levels, can override extrinsic control to some extent, but extrinsic control still plays a significant role in overall blood pressure regulation. The parasympathetic nervous system is not primarily involved in extrinsic control of arteriolar radius, and while oxygen delivery to the tissues is important, it is not the primary focus of extrinsic control.
