Chemical SensesHumans have five senses and often we do not appreciate them. Smell, taste, touch, sight and hearing allow us to navigate the world around us. Two of the most under appreciated senses are the sense of smell and taste. The sense of smell plays a big part in the sense of taste in that together a person can differentiate foods. The perfect meal is comprised of elements having to dowith all of our senses and the pleasant experience is then stored as a memory. Our senses have the ability to trigger memories from very little, such as a smell or a food from your childhood.The way our sense of taste works is through the tongue and the taste buds detect taste in food that has been broken down by saliva. Smell is much more complex in that it goes through different channels and becomes what we smell. The air we breathe in that is not taken into the lungs is what we smell. Smell and taste are closely linked. Taste is made up of only sweet, salty, bitter, savory, and sour relatively simple, but when smell is added to the mix you then have manymore combinations since there are thousands of smells. Smell is made of tens of thousands of smells that elevate the taste of something for example such as the detection of a smokey taste of a meal. Without a sense of smell a person would not be able to differentiate one food from another if they are both of the same taste as in both being salty foods.
