Question

Quizplus · Accepted Answer

During exercise, sympathetic stimulation of the heart and arteriolar smooth muscle is enhanced primarily due to reflexes triggered by the central command (brain anticipation of exercise), muscle chemoreceptors, and mechanoreceptors, not directly because of elevated mean arterial pressure or pulse pressure. These reflexes aim to increase cardiac output and redistribute blood flow to meet the metabolic demands of the muscles, rather than responding to changes in arterial pressures.
