The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
Nasal cavity anatomy. The term "nasal cavity" can refer to each of the two cavities of the nose, or to the two sides combined. CT scan in the coronal plane, showing the ostiomeatal complex (green area) The lateral wall of each nasal cavity mainly consists of the maxilla.
A nose is a sensory organ and respiratory structure in vertebrates. It consists of a nasal cavity inside the head, and an external nose on the face. The external nose houses the nostrils , or nares, a pair of tubes providing airflow through the nose for respiration .

The septal nasal cartilage is also the main structure that provides the orientation of the nose, being the midline structure of the organ. With an offset septal nasal cartilage, the nose will appear crooked to the viewer. A crooked nose can block airflow coming from the nares to the lungs or vice versa. [4]
Vomer of infant. At an early period, the septum of the nose consists of a plate of cartilage, known as the ethmovomerine cartilage.. The posterosuperior part of this cartilage is ossified to form the perpendicular plate of the ethmoid; its anteroinferior portion persists as the septal cartilage, while the vomer is ossified in the membrane covering its posteroinferior part.
The nose is referred to as the nasal region. The mouth is referred to as the oral region. The chin is referred to as the mental region. The neck is referred to as the cervical region. The trunk of the body contains, from superior to inferior, the thoracic region encompassing the chest [1] the mammary region encompassing each breast
Illustration of upper respiratory system. In anatomy, a nasal concha (/ ˈ k ɒ n k ə /; pl.: conchae; / ˈ k ɒ n k iː /; Latin for 'shell'), also called a nasal turbinate or turbinal, [1] [2] is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various other animals.
