WebThe respiratory tract is the path of air from the nose to the lungs. It is divided into two sections: Upper Respiratory Tract and the Lower Respiratory Tract. Included in the upper respiratory tract are the Nostrils, Nasal Cavities, Pharynx, Epiglottis, and the Larynx. WebAir moves in and out of the lungs in response to differences in pressure. When the air pressure within the alveolar spaces falls below atmospheric pressure, air enters the lungs ( inspiration ), provided the larynx is open; when the air pressure within the alveoli exceeds atmospheric pressure, air is blown from the lungs ( expiration ).
