What is the name of the tube that connects the mouth and nose to the larynx?

The tube that connects the mouth and nose to the larynx is known as the pharynx. This anatomical structure plays a crucial role in both the respiratory and digestive systems. It serves as a passageway for air to travel from the nasal cavity and mouth to the larynx, which leads to the trachea and ultimately to the lungs. Additionally, the pharynx is involved in the swallowing process, allowing food to pass from the mouth to the esophagus.

The trachea is the airway that extends from the larynx down to the bronchi, where it branches into each lung, but it does not connect the mouth and nose. The bronchi are the two main branches of the trachea that enter the lungs. The esophagus is the tube that transports food from the pharynx to the stomach, but it does not connect to the larynx and is not involved in the passage of air. Therefore, the pharynx is the correct term for the structure that connects both the mouth and nose to the larynx.
