Work to expand and shrink the thoracic cavity. Two sets of muscles work in opposition. Aid in quiet (passive) and forced inhalation. Result in elevation of the ribs, and the outward expansion of the cavity. Result in depression of ribs, and decrease the size of the thoracic cavity. Diaphragmatic breathing, abdominal breathing, belly breathing or deep breathing. In this type of breathing, the thoracic cavity stays relatively motionless, movement is isolated to the abdominal cavity, and uses more of the abdominal muscles to power the diaphragm. Also part of yoga and meditative practice. Changes in pressure in alveoli relative to the environment during the respiration process. 0 = atmospheric pressure (hg = mercury) At the point where volume increase is the greatest the pressure has been momentarily restored to atmospheric levels.
