Muscles help keep blood flowing normally through the body. How do muscles accomplish this task?
bezimeni [28]

Answer:

Option A, by having a constant supply of blood

Explanation:

Blood that flows to the muscles bring oxygen from the atmosphere to the contracting muscles where it gets consumed.  During large muscle exercise, two physiological needs arise – a) high and prolonged muscle blood flow and b) regulation of blood pressure so that there is adequate perfusion of pressure to all organs. In order to meet both the requirements, the blood flow increases so that the vasoligating muscles do not outstrip the cardiac output.

Hence, option A is correct
