The pharynx serves as a common passageway for both the respiratory and digestive systems. It connects the nasal cavity and mouth to the esophagus and trachea, allowing air and food to pass through. The other options are not common passageways for both systems. The nose only functions in the respiratory system, the trachea only carries air to and from the lungs, and the esophagus only carries food to the stomach.
