How Does the Sense of Taste Work?

Wondering why there is metallic taste in my mouth? The taste we get is the two-phase chemical reaction of our mouth and throat, and our nose. Human beings are born with about 10,000 taste buds on our tongue, throats, and mouth roof. Saliva plays an essential role because it helps to transport the taste we receive in our taste buds. 

We have taste buds with around 10-50 cells that are responsible for initiating the taste action and are replenished in about 7-10 days. Human beings tend to begin to lose their taste buds by reaching the age of 50-60.

Taste sensation initiates with the odors and smells around us that stimulate nerves in a small area high in the nose. All types of smell stimulate the brain and affect the actual flavors of our food. We feel the taste like the food we eat gets mixed with the saliva that activates the taste buds.
