When the body is at rest aprox 15% of blood is supplied to the muscles and the rest goes to the organs.
When the body starts exercising this per cent age can increase to 80-85% and less blood goes to the organs all thoe the amount of blood that goes to the brain stays the same.
Blood being redistributed around the body is called the 'vascular shunt mechanism'
During light exercise redirection of blood to the skin enables the body to get rid of heat and keep cool. Skeletal muscle arterioles and pre-capillary sphincters vasodilate, increasing blood flow to muscles being used and organ arterioles and pre-capillary sphinchters vasoconstrict, temporally reducing blood flow to the organs.
