Human Body : Nose



The function of nose in respiratory system is very important. It is responsible for filtering and inhaling air containing vital oxygen .

The septum divides the nasal cavity to create two equal sized nostrils. The fine hair or cilia in the nose behave like a mechanical filter removing particles from the air we breathe in.

The nose also pre-warms the air we breathe during inhalation to match body’s temperature .


Of course, the nose is also the organ responsible for our sense of smell. The nostrils contain six million cells that are sensitive enough to detect a huge number of different smells. Humans have the ability to detect as many as over one trillion distinct scents.
