The tongue, throat (pharynx), and liver all play roles in the digestive system, but have other roles as well. The tongue helps move food in the mouth and throat, but also functions as a sense organ (taste) and helps make speech. The pharynx functions in both the respiratory and digestive systems, carrying both air to the lungs and food to the esophagus. The liver produces bile that assists in fat digestion, but has many other functions as well in the excretory and endocrine systems.
