Blood Flow Changes During Exercise by Pannir Selva is a document available to read on EtoBox.
During exercise, blood flow through active skeletal muscles increases dramatically up to 15-20 times greater than at rest. This is due to the opening of more capillaries and the release of substances that cause blood vessels to dilate. Sympathetic stimulation also causes some vasoconstriction in the skin and viscera while dilating blood vessels in muscles. This shunts more blood to the exercising muscles. Increased venous return and cardiac output elevate blood pressure to sustain the higher muscle blood fl
