Question

Quizplus · Accepted Answer

The diameter of the arterial blood vessels leading to the muscle has the greatest influence on blood flow to a skeletal muscle during exercise. During exercise, the metabolic demands of the skeletal muscles increase, leading to an increase in blood flow to these muscles. The diameter of the arterial blood vessels leading to the muscle determines the amount of blood that can flow through them to meet the increased demand for oxygen and nutrients in the muscles. The more dilated the vessels are, the more blood can flow through them, providing the necessary nutrients and removing waste products efficiently. Therefore, the diameter of the arterial blood vessels leading to the muscle is the most influencing factor on blood flow during exercise.
