If the arterial blood pressure in the brain is suddenly decreased,the flow through arterioles in the brain will immediately fall and then return to near their original levels due to flow autoregulation.

Question

Quizplus · Accepted Answer

Flow autoregulation is a mechanism by which blood flow through an organ is maintained relatively constant despite changes in perfusion pressure. It is present in many organs including the brain. Therefore, if the arterial blood pressure in the brain suddenly decreases, the flow through arterioles in the brain will immediately fall, but it will return to near their original levels due to flow autoregulation. Thus, the statement is true.
