Question

For both types of exercise, the tidal volumes and breathing rates increased. compared with normal values, did tidal volume or breathing rate increase more during moderate exercise?

A. Tidal volume increased more
B. Breathing rate increased more
C. Both increased equally
D. No significant increase observed

Answer 1

During moderate exercise, both tidal volume and respiratory rate increase. However, tidal volume increases more than respiratory rate.The correct option is A.

Step-by-step explanation:

The respiratory rate and tidal volume both increase during moderate exercise, but one increases more than the other. In this case, the question is asking which one increased more.

Tidal volume refers to the amount of air that is inhaled and exhaled in one breath, while the respiratory rate refers to the number of breaths taken per minute.

During moderate exercise, the body needs more oxygen, so both the tidal volume and respiratory rate increase.

However, the increase in tidal volume is usually greater than the increase in respiratory rate. This means that Option A, tidal volume increased more, is the correct answer.
