Answer :
Final answer:
A decrease in thoracic wall compliance reduces vital capacity in aging individuals, impacting breathing efficiency and lung function.
Explanation:
Decrease in thoracic wall compliance due to the diminished ability to expand the chest is the condition of aging that reduces vital capacity. This decreased compliance makes breathing more difficult and affects the lung's ability to function properly.
As a result, individuals may experience reduced lung capacity and limitations in inhaling and exhaling efficiently. An example of this condition is seen in restrictive diseases like fibrosis.
