Question

Which of the following would increase with exercise?

a. tidal volume and frequency of breathing
b. frequency of breathing
c. tidal volume, frequency of breathing and minute volume
d. minute volume
e. tidal volume

Answer 1

During exercise, both the tidal volume and frequency of breathing increase, leading to an increase in minute volume. Thus, the correct answer is c. tidal volume, frequency of breathing, and minute volume.

Step-by-step explanation:

The question pertains to the changes in respiratory parameters during exercise. During exercise, the respiratory rate and the volume of air per breath typically increase to meet the body's heightened oxygen demands. As such, both tidal volume (the amount of air inhaled or exhaled in a single breath during normal breathing) and frequency of breathing (respiratory rate), as well as minute volume (the total volume of air inhaled and exhaled per minute), will increase. So, the correct answer is c. tidal volume, frequency of breathing, and minute volume.
