Tongue

The tongue is a muscular organ in the mouth that is responsible for various functions, including mastication, licking, swallowing, and speech.

In humans, the tongue is divided into two parts: the oral tongue and the base of the tongue. The oral tongue is the part of the tongue that is visible in the mouth, while the base of the tongue is the part that is attached to the floor of the mouth.

The tongue is covered with a thin layer of the mucous membrane, which is coated with saliva. The saliva contains enzymes that break down food particles, as well as bacteria that help to keep the mouth clean. The tongue also has thousands of taste buds, which are responsible for the sense of taste.

The tongue is a very important organ in the human body, and it plays a vital role in the digestive process, as well as in speech and communication.
