WebMar 22, 2024 · Blood flow regulation is one of the most interesting aspects of human physiology. When we perform high-intensity exercise, we utilize oxygen faster than it can be supplied to the skeletal muscle. As a result, there is net deoxygenation of the skeletal muscle. In response to this hypoxia in the skeletal muscle, we experience ‘metabolic ... WebDuring exercise, the body's demand for the oxygen needed in cellular respiration increases, and this requires the body to do some adjustments. The cardiac output and pulmonary blood flow increase, while the pulmonary vascular resistance decreases. The result is an increased space of the lung that is perfused, which decreases physiologic dead space and increases …
