How the Tongue Work
The human tongue is made up of a group of muscles and taste buds that work together to recognize taste.
The average adult tongue has 10,000 taste buds ,which are tiny bumps located on the tongue.
Tiny hairs on the end of the taste buds tell us whether food is sweet,sour,bitter,or salty.
The taste buds send messages to the brain as chemical from the food enter the nose.
Together,the taste buds and nose tell the brain exactly what the tongue is tasting.
This complex system helps human survive by recognizing which foods are safe and which might be dangerous
