Through which tube does air pass before entering the lungs?

Answer and explanation

Correct answer: Trachea

Air enters through the nose or mouth, passes through the pharynx and larynx, and then travels down the trachea, also called the windpipe, before reaching the bronchi and lungs. Hence option A is correct. The oesophagus carries swallowed food to the stomach, the ureter carries urine from a kidney to the urinary bladder, and an artery transports blood away from the heart.
