Current Question (ID: 14317)

Question:

The amount of air that enters the lungs during normal, restful breathing is called the______.

Options:

1. Vital capacity
2. Tidal volume
3. Total lung capacity
4. Expiratory reserve volume

Solution:

Tidal volume is the amount of air that moves in and out of the lungs during normal, quiet breathing. It is typically around 500 mL in healthy adults but can vary based on factors such as age, sex, and physical activity level. Option (1) Vital capacity refers to the total amount of air that can be exhaled after taking the deepest breath possible. Option (3) Total lung capacity is the total volume of air that the lungs can hold, including both the air that can be inhaled and the air that remains in the lungs after maximum exhalation. Option (4) Expiratory reserve volume is the amount of air that can be forcefully exhaled after a normal exhalation.
