Which organ carries air to the lungs?

• A. Esophagus
• B. Gallbladder
• C. Trachea
• D. Larynx

Answer: (C)

Air is carried down the airway through the trachea, the windpipe that acts as the main conduit to the lungs. It stays open thanks to cartilage rings and is lined with mucus and tiny hairs (cilia) that trap and move particles out of the airway. From the trachea, air splits into the bronchi and into the lungs where gas exchange happens. The esophagus handles swallowing food and lies behind the trachea, the gallbladder stores bile and has no role in breathing, and the larynx sits above the trachea and helps with voice and protecting the airway during swallowing, but the actual tube that carries air to the lungs is the trachea.
