Question

Rafi said smell also increase our appetite can you support this statement .how?

Answer 1

Taste and smell are intimately entwined.This close relationship is most apparent in how we perceive flavours of food.During cough and cold ,only the taste not the food odours are being detected,that is why we can not make out the differences in tastes of certain food food items during cough and cold.
Interactions between the senses of taste and smell enhance our perceptions of food we eat.
when we smell ,the air borne substances get dissolved in the watery film of nasal mucus.The olfactory receptors in nose which trigger signals in the form of nerve impulses to the brain where smell is detected.similarly as we take food into our mouth the taste buds sends signals to the brain.picking up the slight differences in smell the food tastes are identified in our brain.
Hence we can say smell also increase our appetite.
