Nose Facts

Did you know we all have four nostrils? We have two you can see, two you can’t. This discovery came from watching how fish breathe. Fish get their oxygen from water, most of them have two pair of nostrils, a forward facing set for letting water in and two for letting water out.

Our other two nostrils, migrated toward the back of the head, to become internal nostrils called ‘choannae’ – Greek for ‘funnels’. They connect to the throat and allow us to breathe through our noses.
