Question

Quizplus · Accepted Answer

During exercise, the body undergoes several physiological adjustments to meet the increased demand for oxygen and nutrients in the active muscles. These adjustments include vasodilation at the active skeletal muscles to increase blood flow, an increase in venous return due to the muscle pump effect, an increase in both cardiac output and stroke volume to pump more blood throughout the body, and a decrease in tissue perfusion to the digestive system as blood is redirected to the muscles. Angiotensin II, a peptide hormone, is primarily involved in the regulation of blood pressure and fluid balance. Its release is not a direct response to exercise; instead, it is more closely associated with the renin-angiotensin system's role in blood pressure regulation and not a typical response to physical activity.
