Detailed explanation-1: -First, because the metabolic costs of muscle contraction can be high and prolonged, skeletal muscle blood flow needs to be matched to the metabolic demands of the contracting muscles. Second, regulation of blood pressure is also needed to ensure there is adequate perfusion pressure to all organs.
Detailed explanation-2: -During exercise, your muscles have to work harder, which increases their demand for oxygen. This is why your breathing and heart rates increase: To help pull more oxygen into your bloodstream. As you exercise, the oxygen that reaches your muscles never leaves, but rather converts the available glucose into ATP.
Detailed explanation-3: -Oxygen makes its way into red blood cells, where a molecule called hemoglobin transports it to the muscles-and everywhere else in your body it needs to go. Your heart must pump harder to send all that oxygen-rich blood to your muscles. The more the heart works, the more efficient it gets at its job.
