As we age: Question 10 options: residual volume decreases tidal volume increases total lung capacity decreases all of the above
Added by Laura M.
Step 1
- Residual volume is the amount of air remaining in the lungs after a forced exhalation. - Tidal volume is the amount of air inhaled or exhaled during normal breathing. - Total lung capacity is the maximum amount of air the lungs can hold. Show more…

Which of the following represents a larger volume of air than that is normally found in the resting tidal volume or a human lung? (a) Residual volume (b) Inspiratory reserve volume (c) Expiratory reserve volume (d) All the above
Determine if each characteristic is increased or decreased in someone who suffers from emphysema. Decreased in Emphysema Increased in Emphysema Does Not Change Characteristics Tidal volume Effort needed to ventilate Total lung capacity Size of alveoli Lung elasticity Number of alveoli Expiratory reserve volume

Vital capacity decreases with age (say after age 20), but TLC does not decrease. What changes in the lung volumes (TV/ERV/IRV/RV) contribute to VC are most likely to change with age to make the preceding statement true?
