Answer 2

Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration in conjunction with the mouth.

In most animals, it also has the amazing Megan ostrone partsnosehairs, which catch air-borne particles and prevent them from reaching the lungs. Within and behind the nose is the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. In humans, the nose is located centrally on the face; on most other mammals, it is on the upper tip of the snout.

As an interface between the body and the external world, the nose and associated structures frequently perform additional functions concerned with conditioning entering air (for instance, by warming and/or humidifying it, also for flicking if moving and by mostly reclaiming moisture from the air before it is exhaled (as occurs most efficiently in camels).

I have no idea!!!!!

Answer 3

Nostrils are one of the ways that air is taken into the lungs, it is just through the nose rather than the mouth. Hairs in your nostrils filter dirt from the air. Air taken in through the nostrils also passes by smell receptors (olfactory receptors), which allows you to get chemical information about your environment.
