Is the tongue considered a primary organ of the GI tract?

The tongue is not classified as a primary organ of the gastrointestinal (GI) tract. The primary organs include those directly involved in the digestive process, such as the mouth, esophagus, stomach, intestines, and anus. While the tongue plays a crucial role in the digestive process by aiding in the mechanical breakdown of food, facilitating swallowing, and contributing to taste sensation, it is considered an accessory organ rather than a primary organ of the GI tract. Accessory organs support digestion but do not form the main structure of the digestive pathway itself. This distinction clarifies why the correct answer is that the statement is false.
