Usually air is breathed in and out through the nose. The nasal cavities (between the nostrils and the pharynx) are quite narrow, firstly by being divided in two by the nasal septum, and secondly by lateral walls that have several longitudinal folds, or shelves, called nasal conchae,[8] thus exposing a large area of nasal mucous membrane to the air as it is inhaled (and exhaled). This causes the inhaled air to take up moisture from the wet mucus, and warmth from the underlying blood vessels, so that the air is very nearly saturated with water vapor and is at almost body temperature by the time it reaches the larynx.[7] Part of this moisture and heat is recaptured as the exhaled air moves out over the partially dried-out, hygroscopic, cooled mucus in the nasal passages, during breathing out. The sticky mucus also traps much of the particulate matter that is breathed in, preventing it from reaching the lungs.

The diaphragm is primarily innervated by the phrenic nerve(膈神经) which is formed from the cervical nerves(颈神经) C3, C4 and C5.
