What is the passage for air moving in and out of the lungs?
Answer and explanation
Correct answer: Trachea
The respiratory system provides a passage for air and enables gas exchange. Air entering through the nose or mouth passes into the trachea, which divides into bronchi leading to the lungs. Hence option A is correct. The food pipe carries swallowed food, the ureter carries urine from a kidney, and an artery carries blood, not air.
