Question

Quizplus · Accepted Answer

During strenuous exercise, blood flow increases to both the heart and skeletal muscles due to local control factors. Local control factors such as increased metabolic demand, decreased oxygen levels, and the release of vasoactive substances like nitric oxide cause arterioles in the working muscles to dilate and increase blood flow to those areas. The heart also experiences increased blood flow due to increased cardiac output needed to meet the demands of the exercising muscles. The brain is not a major priority for increased blood flow during exercise, and reflex control factors do not play as significant of a role in regulating blood flow during exercise compared to local control factors.
