Speaking of nose, do you know how it works?
00:00:00
If not, don't worry my friends.
00:00:04
Let's be nosy and find out some interesting facts about an impressive part of our body we call the nose.
00:00:07
Zoom in!
00:00:16
Well friends, as we all know that your nose lets you smell, breathe and is the main gate for the respiratory system.
00:00:19
And it all starts with the nostrils, which is the entrance point of your nose.
00:00:28
Separated by a wiggly wall in the middle called the septum.
00:00:35
Made of a very thin piece of skin and bone known as the cartilage.
00:00:40
Right behind your nose is a space called the nasal cavity that connects with the back of the throat.
00:00:47
The snot works with your hair to trap unwanted small particles like dust and germs that could be harmful to your lungs.
00:00:55
When this captured dirt dries up along with mucus, you get boogers.
00:01:06
So, we need to appreciate these boogers as they are formed in the process of protecting your lungs.
00:01:13
But sometimes your nose traps something you wanted to get rid of.
00:01:21
And you know what happens next?
00:01:27
You sneeze!
00:01:30
Well, the reason you can smell different things around you is because of the olfactory epithelium.
00:01:33
The olfactory epithelium contains special receptors that notice the smell..
00:01:40
and sends the signals along the olfactory nerve to the olfactory bulb.
00:01:47
And finally, those signals go to the other parts of the brain
00:01:53
to be interpreted as a smell you may recognize.
00:01:58
Like food, fruits, flowers or smelly socks.
00:02:03
Truly amazing, isn't it?
