6.1.4  Tongue

The tongue is a muscular organ which is important in enabling us to taste different types of food, roll chewed food into a ball for easy swallowing, and communicate with others through speech. A healthy tongue is pink and clean, with hundreds of tiny ‘taste buds’ visible on its surface (Figure 6.5).
