Detailed explanation-1: -During exercise, the cardiovascular system redistributes the blood so that more of it goes to the working muscles and less of it goes to other body organs such as the digestive system. This redirection of blood flow is caused by a mechanism (or process) called the vascular shunt mechanism.

Detailed explanation-2: -Blood flow in skeletal muscle is mainly regulated via changes in flow resistance in the intramuscular arterioles. The latter is primarily dependent on the arteriolar radius which is controlled by the contractile state (tone) of the vascular smooth muscle cells.
