Quizplus · Accepted Answer

As you increase the speed on the treadmill, your body's demand for oxygen increases, leading to an increase in minute ventilation (A), oxygen delivery to muscles (C), oxygen extraction from the blood by muscles (D), and body heat production (E). However, arterial PCO₂ (B) is regulated by the body's acid-base balance and does not increase as a direct result of exercise intensity.
