Which of the following is an effect of aging on the respiratory system?
A) Vital capacity is unchanged.
B) Minute ventilation rates increase.
C) Residual volume increases.
D) Gas exchange in the lungs remains unchanged.
Residual Volume
The amount of air left in the lungs after a person has exhaled completely.
Aging
The natural and inevitable process of growing older, characterized by gradual changes in the biological, psychological, and social structures of individuals.
Minute Ventilation
Product of tidal volume times the respiratory rate.

Final Answer :
C
Explanation :
Residual volume increases with age due to changes in the structure and function of the lungs, such as decreased elasticity and changes in chest wall dynamics, which can lead to an increase in the amount of air remaining in the lungs after a maximal exhalation.
