4. 2 you can see, 2 you can't. This was found out by observing how fish breathe. Fish get their oxygen from the water. Most of them have 2 sets of nostrils, a forward facing set for letting water in and a pair of "exhaust pipes" for letting it out again. If humans evolved from fishes, where did the other two go? The answer is that they moved back inside the head to become internal nostrils called choannae (Greek for funnels). These are connected to the throat and are what allow us to breathe through our noses.

In humans, there are typically two nostrils, one on each side of the nose. These nostrils are responsible for allowing air to pass in and out of the respiratory system.
