Question 1 of 5
Gas exchange occurs in which of the following structures?
Correct Answer: C
Rationale: Gas exchange occurs in the alveoli, tiny air sacs in the lungs where oxygen is taken up by the blood and carbon dioxide is released. The alveoli have thin walls and a large surface area, allowing for efficient exchange of gases. The bronchi, nasal passages, and larynx are all involved in the passage of air to and from the lungs but do not participate directly in gas exchange. The bronchi are airways that branch off from the trachea, the nasal passages warm and filter air, and the larynx houses the vocal cords.
Therefore, the correct answer is C: alveoli.
