Apparently humans actually have four nostrils. Is this true and if it is where are they?
@invisable bassist,
I only have two. Who the hell told you we have four? Are there two somewhere on the body I haven't noticed?
Yep. It's four.
Nostril
From Wikipedia, the free encyclopedia
Human nostrils
Humans have two external with two additional nostrils inside the head. These internal nostrils called "choana" connect the nose to the throat aiding in respiration. Scientists believe they migrated back inside as evidenced by the discovery of "Kenichthys campbelli", a 395 million-year-old fossilized fish which shows this migration in progress. It has two nostrils between its front teeth, similar to human embryos at an early stage. If these fail to join up it causes a 'cleft palate'.[2]
@edgarblythe,
If they are INSIDE then I don't consider them nostrils at all. Nostrils are those things we flair when we're pissed off.
@NickFun,
Well, my nostrils are flaring. All four of them. I am angry because I now have two more to blow. No wonder noses make so many boogers.
