External nostrils, also known as the nasal openings or nasal passages, are the two openings on the nose that allow air to enter and exit the respiratory system. They are located at the base of the nose, just above the upper lip. The external nostrils are responsible for filtering, warming, and moistening the air we breathe before it reaches the lungs. They also play a role in our sense of smell, as they contain olfactory receptors that detect and interpret different scents.

Glottis is a part of respiratory passage and it opens into larynx. Near the glottis is a flap like structure called epiglottis. At the time of swallowing of food this flap covers the glottis to prevent the entry of food particles into it.
