Smell

For writing we have been doing Explanations about 1 of the 5 senses


Smell
Smell is a very useful part of your body it helps you in your everyday life. It is one of your 5 senses. Smell also helps you taste.


How  does your nose work ?
In your nose you have a smell device. In the smell device there are more the 10 million scent receptors. And dog can smell 20 times better than a human.  Tiny Odor molecules pass through the nose and into the brain. Every month your scent cells are renewed it is just like getting a new nose. Your nose detect much more than good smells it can also detect bad nasty smells like chemicals.

Why do we need our nose ?
We need our nose so we can taste our food. Smell makes our food taste better. Also in your nose is mucus the green slimy stuff also known as Boogers. You produce almost over a liter of mucus a day. They aren't just there for you to pick they keep the dust and pollen from getting in to your lungs. Also your nose hairs help trap the dust. Another name for Nose hairs is Nasal hair. In an average lifetime you grow about 2 metersz of nasal hair. You can smell much better in spring and summer, due to the moisture in the air and some certain smells can bring back old memories .

Do we need a nose?
Yes you do need a nose Because without a nose you would not be able to taste anything sweet, sour, salty. NOTHING. Without a nose it would be very hard to breathe because you mainly breathe through your nose. Before the air goes it your lungs the nose warms it up so that you lungs don’t freeze. On average a man's nose is bigger than a woman's nose  but a Woman's sense of smell is much better than a Mans.


So altogether you need a nose to Smell yummy homemade baking, Taste sweets and lollies and Breath in air.
