Question
What happens to the ventilation rate during exercise?
Briefly describe and explain how the chemoreceptors work during exercise
.
Expert Solution
Step 1
Pulmonary ventilation or breathing is the process of air flowing into the lungs during inspiration (inhalation) and out of the lungs during expiration (exhalation).
Step 2
Pulmonary ventilation increases during physical activity because of a rise in tidal volume and respiratory rate to meet increased oxygen demands. Oxygen delivery during strenuous exercise is limited by cardiovascular function.
