Hide | Show

જવાબ : The sense of smell is far more complex than the sense taste because there is not only one smell for one object. It is very difficult to prepare a table of objects and their standard smells.

They travel from mouth, down the throat and up again along passages leading nasal cavities. We smell when we inhale and we smell flavours when we exhale.

How do we Smell?

Hide | Show

જવાબ : It is not the tongue but our nose that reveals the true flavour of food. Flavours have a back door entry to nose. They travel from mouth down the throat and up again along the air passage leading to nasal cavities. We ‘smell’ when we inhale and we sense flavours when we exhale. When we want to check the odour, we sniff. Sniffing carries the odour filled air upward to olfactory area located high up the nasal cavity. When we chew the food, warm vapour is released and flavours are detected. Higher the temperature of a substance, the more molecules are given off and intense odours are felt. Mostly, there is never only one smell for one object. Women have more acute sense of smell than men have. The sense of smell becomes dull with ageing, smoking and drinking alcoholic beverages.
