Saliva is needed for the proper functioning of the tongue. A dry tongue can't taste a thing so saliva helps the tongue and our sense of taste by keeping it wet. Saliva moistens food and helps to break it down, which in turn makes it easier for the tongue to push the food to the back of the mouth for swallowing.
Anatomical terminology. [edit on Wikidata] The tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication, and is used in the act of swallowing. It is of importance in the digestive system and is the primary organ of taste in the gustatory system. The tongue's upper surface (dorsum) is covered in taste buds housed in numerous lingual papillae.
