Nervous system centers set the normal resting rate and depth of respiration. Which factors below can alter this normal respiratory rate and depth?

Question

Quizplus · Accepted Answer

C is correct because exercise, changes in blood CO2 levels, and changes in the pH of the blood can all alter the normal respiratory rate and depth. Exercise increases the demand for oxygen and the production of CO2, leading to changes in respiratory rate and depth to meet the body's needs. Changes in blood CO2 levels and pH directly influence the respiratory centers in the brain to adjust breathing to maintain homeostasis.
