What is taste?

 Taste is when you determine the flavor and palatability of food. Taste gives you signals of dangerous gases and toxic food. All over your tongue, there are little bumps called taste buds. There are four different types of taste buds. You can taste sweets in the front of your tongue and sour taste at both sides of your tongue At the back, you taste bitter things. All over your tongue, you taste salty things 


Every time we breathe, air flows through the nasal cavity where the air flows down through the back of the mouth into the throat. Some air that flows into your mouth passes the olfactory organs. Any odor molecules in the air will past by and get stuck to the mucus in your nose. The sensory hairs sense the odor and transmit messages to your brain. Your brain, therefore knows the odor. The smell receptor cell is located high up behind your nose. The receptor is sensitive to chemicals in the mucus in your nose.
