1. Taste --- What is the function of Taste?
To protect your body from unsafe foods.
Taste Buds: most of our taste buds are on our tongue.
Basic Tastes: Sweet, salty, sour and bitter.
Your sense of taste protects you from unsafe foods.
If you ate poisonous or rotten food --- you would spit it out immediately because you’d recognize it was bad. Obviously – the food never enters your body or stomach.
In addition: your sense of taste helps you maintain a consistent chemical balance in your body.
Liking sugar, for example satisfies your body’s need for carbs and minerals.
Similarly --- eating sour foods such as oranges and lemons supplies your body with essential vitamins.

2. Taste Buds: our mouth contains about 10,000 taste buds which are mostly
located on and around the tiny bumps on your tongue.
Every taste bud detects 5 primary tastes:
Sour
Sweet
Bitter
Salty
Umami (salts of certain acids (MSG)
Each of our taste buds contains specialized receptor cells.
Each receptor cell has a tiny taste hair that checks out the food chemicals in your saliva.
After these taste hairs are stimulated they send nerve impulses to your brain.
Each taste hair responds to one of the 5 basic tastes.
