The myogenic mechanism counters changes in blood flow through capillary beds by altering arterial resistance.

Question

Quizplus · Accepted Answer

The myogenic mechanism is a type of autoregulation that helps to maintain constant blood flow through capillary beds. It does so by altering the resistance of the arterioles that feed into the capillary network, in response to changes in pressure or flow. Specifically, when blood pressure increases, the arterioles constrict to limit the amount of blood flow into the capillaries, while when blood pressure decreases, the arterioles dilate to increase flow. This allows the capillary beds to receive a reliable and consistent supply of blood, despite changes in systemic pressure or demand.
