Which physiological change is associated with aging?

• A. Increased lung capacity
• B. Diminished capacity of lungs and bladder
• C. Heightened cognitive function
• D. Improved visual and auditory capabilities

Answer: (B)

The physiological change associated with aging is diminished capacity of the lungs and bladder. As people age, various physiological systems undergo changes that can impact function. Specifically, lung capacity may decrease due to a reduction in elastic recoil of the lung tissue and the chest wall, which lessens the efficiency of gas exchange. Additionally, the muscles that support bladder control can weaken over time, leading to issues such as increased frequency of urination and incontinence. In contrast, increased lung capacity, heightened cognitive function, and improved visual and auditory capabilities are generally not accurate representations of typical physiological changes associated with aging. Instead of improvements or increases, aging often leads to declines in these areas.
