SMELL

Smell is one of the five human senses.

The senses keep us informed of our enviroment.

Smell allow us to identify many different smells and know a lot of things, for example existence of fire, contaminated food...
We can identify 10.000 different smells.

The nose is the orgam of smell.

The external parts of the nose are two holes called nostrils.

The air that we breathe, goes through the nasal cavity to the olfatory area when we can found yellow pitituary.

In this yellow zone we have got nerve endings which send impulses to the olfatory bulb.

This bulb indentifies smells and send information to the brain.

The sense of smell is connected to the sense of taste. For example, when you are ill, you can´t smell well and all food have the same flavour.
