pogonyaev

Answer: autonomic nervous system

Explanation:

Pulmonary ventilation increases because of a rise in tidal volume and respiratory rate to meet increased oxgyen demand.oxygen delivery during strenuous exercise is limited by cardiovascular function.

During exercise, there is an increase in physical activity and muscles cell respire more than they do when the body is at rest. The heart rate of breathing increases and this make more oxgyen to absorb into the blood and more carbon dioxide is removed
