All of the following are changes seen in the respiratory system with aging, except
A) decreased vital capacity.
B) decreased maximum minute ventilation.
C) increased dead space.
D) decreased inspiratory reserve volume.
E) decreased lung compliance.
Dead Space
Areas in the respiratory system that do not participate in gas exchange, including the nasal cavities, trachea, and bronchi.
Lung Compliance
Lung compliance refers to the ease with which the lungs can be expanded, determined by the elastic resistance of the lung tissue and chest wall to stretching during inhalation.
Inspiratory Reserve Volume
The additional amount of air that can be inhaled after a normal inhalation, contributing to lung capacity.

Final Answer :
E
Explanation :
Lung compliance actually increases with aging due to changes in the chest wall and the lung tissues, making the lungs more compliant (easier to inflate). This is in contrast to the other options, which accurately describe typical age-related changes in the respiratory system.
