The respiratory system is made up of a set of anatomical structures, whose function is to supply the body with oxygenated air and expelling carbon dioxide. The air passing through these structures has to be conditioned before reaching the main units of the respiratory system. This conditioning consists of heating, humidification and removal of particles. The respiratory system consists of the different organs involved in the gas exchange and is divided into upper airway, which has the driving-, humidification- and filtrationfunction of the atmospheric air and lower airways that perform the exchange of blood gases and tissues through the lungs. The respiratory gear consists of: nose, pharynx, larynx, trachea, bronchi, lungs and alveoli and is distributed in upper and lower airways. The UA is the structure, that has more relevance in the associated processes of sleep breathing disorders.
