In pulmonary ventilation, air is inhaled through the nasal and oral cavities (the nose and mouth). Since the atmospheric is relatively constant, creation of pressure gradient depends upon the intrapulmonic pressure being alternately lower and The work of breathing is done by the diaphragm and the intercostal muscles, located between the ribs.
