Which statement correctly explains why respiration rate elevates with exercise as compared to at rest? 1.Oxygen from the blood diffuses into the alveoli for expulsion through exhalation at a faster rate Inguinal nodes 2.Carbon dioxide from the blood diffuses into the alveoli for expulsion through exhalation at a faster rate 3.Oxygen from the alveoli diffuses into the capillaries for expulsion through exhalation at a faster rate 4.Carbon dioxide from the alveoli diffuses into the capillaries for expulsion through exhalation at a faster rate
