Inhalation

From Wikinfo

Inhalation is the movement of air from the external environment, through the airways, into the alveoli during breathing.

During inhalation, air passes through either the nose or the mouth into the pharynx (throat). The pharynx attaches to the larynx, which is the first element of the airways.
