What is the internal nostrils?
The internal nostrils, also known as the choanae, are openings located at the back of the nasal cavity that connect it to the throat (pharynx). They play a crucial role in the respiratory system by allowing air to flow from the nasal passages to the throat and subsequently to the lungs. The internal nostrils also help in filtering, humidifying, and warming the air before it reaches the lungs. Additionally, they assist in the drainage of mucus from the sinuses.

How many nostrils are present in man?
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.
