Answer:
The tongue is an accessory organ of the digestive system, located in the mouth.
It is a muscular organ that assists in the ingestion of food, manipulation of food, and the beginning of the digestive process.
It is covered by a mucous membrane, which is kept moist by saliva, and is richly supplied with taste buds.
The tongue also helps in speech by forming the sounds of speech and aiding in the articulation of words.
