Question

Quizplus · Accepted Answer

As people age, their chest size generally decreases due to a loss of elasticity in the chest wall and a decrease in muscle mass. This can lead to a decrease in lung function and capacity. Therefore, option D is the correct answer. Option A is incorrect because lung capacity actually decreases with age. Option B is also incorrect because the lungs become less elastic, making it harder to breathe. Option C is incorrect because there is no evidence that the diaphragm strengthens with age.
