Which row correctly shows the areas of the gas exchange system that contain cartilage, ciliated epithelium and goblet cells?
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
It is a fact that bronchioles don't have cartilage, so options A and C are incorrect. Goblet cells are mucus secretory cells in the gas exchange system, and since alveoli don't contain mucus they have no need for goblet cells, so option B is also incorrect. This leaves option D which is the correct answer.

About Human Respiratory System
The human respiratory system conducts air to the alveoli, where oxygen and carbon dioxide exchange occurs across thin respiratory surfaces. Questions cover the nasal passage, trachea, bronchi, lungs, diaphragm and intercostal muscles, ventilation mechanics and gas transport, while distinguishing breathing and gaseous exchange from cellular respiration.
