Quizplus · Accepted Answer

Aging affects the respiratory system in several ways: Peak airflow and gas exchange decrease due to changes in lung structure and function. Respiratory muscles, including the diaphragm, weaken over time, affecting breathing efficiency. Additionally, the effectiveness of lung defense mechanisms declines, making older adults more susceptible to respiratory infections and diseases. Lung surfactant levels typically do not increase with age, and tidal lung capacity usually decreases rather than increases, making options C and E incorrect.
