'''Nose'''

The '''nose''' is a part of the [[anatomy]] of humans and many animals that is involved in breathing and the sense of [[smell]]. It also contributes to the sense of [[taste]].

== Structure ==
The nose is made up of bone, cartilage, and skin. The [[nasal bone]] forms the bridge of the nose, while the rest of the structure is made up of cartilage and skin. The inside of the nose is lined with [[mucous membrane]].

=== External nose ===
The external nose is the visible part of the nose on the face. It is made up of the nasal bone and cartilage. The nostrils (also known as nares) are the openings to the nasal cavity.

=== Internal nose ===
The internal nose is the nasal cavity, which extends from the nostrils to the [[nasopharynx]]. It is divided into two nasal passages by the nasal septum. Each nasal passage is lined with mucous membrane and has three [[nasal conchae]] or turbinates.

== Function ==
The nose has two main functions: breathing and smelling. It also contributes to the sense of taste.

=== Breathing ===
The nose is the primary organ of respiration. It filters, warms, and humidifies the air we breathe.

=== Smelling ===
The sense of smell (olfaction) is mediated by the [[olfactory epithelium]] in the roof of the nasal cavity.

== Clinical significance ==
The nose can be affected by a variety of conditions, including [[nasal congestion]], [[rhinitis]], [[sinusitis]], [[nasal polyps]], and [[nasal fracture]].
