Thank Your Gustatory Receptor Cells
That’s science lingo for taste buds! Our taste buds perceive four basic tastes: sweet, salty, sour, and bitter. One of their functions is to keep your body from unsafe food chemicals. There are tiny taste hairs that check out food chemicals in your saliva. When these taste hairs are stimulated, they send nerve impulses to your brain. So if you ate poisonous or rotten food, you would most likely spit them out immediately – that way you stop them from entering your stomach.
