Which structure is the windpipe?

Explanation:
The windpipe is the trachea. It’s the main airway that carries air from the larynx down to the bronchi and into the lungs. The trachea is a flexible tube reinforced by C-shaped cartilage rings to stay open, with a lining of ciliated cells that move mucus out of the lungs. The larynx sits above it and is the voice box; the esophagus runs behind it and carries food downward; the diaphragm is the breathing muscle at the base of the chest. So the structure that functions as the windpipe is the trachea.
