Which of the Following Age-Based Changes is False

Question

Which of the following age-based changes is false?
A) The lungs lose elastic tissue.
B) The lung's compliance changes.
C) Vital capacity increases.
D) Respiratory muscles weaken.
E) Costal cartilages become more flexible.

Accepted Answer

Vital capacity actually decreases with age due to the loss of elastic tissue in the lungs and changes in compliance, as stated in options A and B. Option D is also true, as respiratory muscles weaken with age. However, option E is false as costal cartilages become less flexible with age, leading to a decreased ability to expand the chest for adequate breathing.
