Olfaction and tasteEdit

Odour contributes to taste as trigeminal receptors together contribute to flavor.

The human tongue can only distinguish among 7-8 distinct types of taste, while the nose can distinguish among hundreds of substances. This is the reason why food has little flavor when your nose is blocked, as from a cold.
