The tongue is only the strongest muscle in proportion to its actual size. The tongue is like the heart, it is always working. It constantly pushes the saliva down your throat, even during your sleep.

It plays a very important part in digestion. It also continuously moves and contorts itself to help you form the sounds that you need for most forms of communication. Without a tongue, you would not be able to communicate properly. When it isn’t doing all of this, it also helps to drain out germs.
