Autoregulation of tissue blood flow in response to an increase in arterial pressure occurs as a result of which of the following?
A)Decrease in vascular resistance
B)Initial decrease in vascular wall tension
C)Excess delivery of nutrients such as oxygen to the tissues
D)Decrease in tissue metabolism

Question

Quizplus · Accepted Answer

Autoregulation involves mechanisms that adjust blood flow to meet the metabolic needs of tissues. An increase in arterial pressure can lead to excess delivery of nutrients like oxygen, which triggers vasoconstriction to reduce blood flow and maintain homeostasis.
