The enlargement of the thoracic cavity’s vertical dimension by the contraction of the diaphragm.

Its two horizontal dimensions by the lifting of the front and sides of the ribs, causes the intrathoracic pressure to fall. The lungs’ interiors are open to the outside air, and being elastic. Therefore expand to fill the increased space. The inflow of air into the lungs occurs via the respiratory airways (Fig. 2). In health, these airways begin with the nose. It is possible to begin with the mouth, which is the backup breathing system.

However, chronic mouth breathing leads to, or is a sign of, illness. They end in the microscopic dead-end sacs called alveoli, which are always open. Though the diameters of the various sections can be change by the sympathetic and parasympathetic nervous systems. The alveolar air pressure is therefore always close to atmospheric air pressure (about 100 kPa at sea level) at rest. With the pressure gradients that cause air to move in and out of the lungs during breathing rarely exceeding 2–3 kPa.

The changes in the composition of the alveolar air during a normal breathing cycle at rest.

The scale on the left, and the blue line, indicate the partial pressures of carbon dioxide in kPa. While that on the right and the red line, indicate the partial pressures of oxygen. Also in kPa (to convert kPa into mm Hg, multiply by 7.5).

The volume of air that moves in or out (at the nose or mouth) during a single breathing cycle is called the tidal volume. In a resting adult human it is about 500 ml per breath. At the end of exhalation the airways contain about 150 ml of alveolar air which is the first air that is breathe. Back into the alveoli during inhalation.
