MEDICAL PHYSIOLOGY

Detailed explanation-1: -Skeletal muscle blood flow increases dramatically, while blood flow to other tissues, especially the abdominal viscera and kidneys, is reduced. During heavy exercise, the vast increase in cardiac output is directed almost exclusively to contracting skeletal and cardiac muscles.

Detailed explanation-2: -The largest of these increases in blood flow occurs in the exercising skeletal muscles, owing to their mass relative to the other tissues.

Detailed explanation-3: -Constant cerebral blood flow (CBF) is vital to human survival. Originally thought to receive steady blood flow, the brain has shown to experience increases in blood flow during exercise.

Detailed explanation-4: -Muscles require more energy during exercise. Additional oxygen and glucose are needed to release the energy. Blood flow increases to supply these to muscles faster. Respiration also increases to allow more oxygen to be transported to the muscles.

Detailed explanation-5: -Likewise, thermal stress, such as hot yoga and sauna help get more blood to the brain. Exercises involving hydrostatic stress, like aqua aerobics, also increase blood flow because the pressure of the water pushes more blood up and into the brain.
