Functions of the nose
Nose is the gateway to the airways, air into the lungs must pass through the nose, so that the nose is also specific to adapt to that task. Nasal mucosa is the respiratory mucosa with hairy epithelial cells and glandular secretions. The nasal cone is shaped like a luminaire to increase the area of contact of the air through the nasal mucosa. The nose performs three functions: breathing - sniffing and pronouncing.
The respiratory function is achieved through the role of warming through the circulatory system, which causes the lower back (up to 33 ° C) before passing through the nasal cavity. Moisturizes and cleanses the system of mucus on the surface of the nasal mucosa, in the mucous layer of lymphocytes, macrophages ... which capture dust, bacteria ... create nasal leakage at the front door nose or be transported to the rear nose.
The function of the olfactory senses (striatum 1), located on the upper floor of the nose, diffuses into a region that makes the mucosa yellowish, called olfactory.
Nose also acts as a resonance and secretion of some nasal sounds such as B, D, and P so if patient asphyxiate it will be difficult to pronounce these sounds.
