THE SMELL
The smell is one of the five senses of the human body, its the responsible for detecting odors.
INFORMATION
These molecules reach the olfactory mucosa, which consists of three characteristic types of cells: olfactory sensory cells, supporting cells and basal cells, which divide about once a month and replace the dying olfactory cells.
the human nose can smell more than 10.000 diferents odors.
The 20 or 30 million human olfactory cells contain, at its front end, a small head with about 20 small sensory filaments (cilia).
The aqueous nasal mucus transports aromatic molecules to cilia using binding proteins; cilia transform the chemical signals of different flavors in electrical responses

THE PARTS OF THE NOSE
- Nostrils: cavities where oxigen enters.
- Meatus: humidifies the air, also heats.
- turbinates: Dampen the air, so warm, meets function with the meatus .
- Sinus: they are cavities found in bones near the nose, such as frontal, sphenoid, ethmoid and maxillary.
- Greatly affect breathing, warm, and processes of phonation.
