What is Respiratory muscles

As respiratory muscles those are skeletal muscles called that in an expansion or contraction of the rib cage and thus lead to an inhalation and exhalation. The most important respiratory muscle is the diaphragm ( diaphragm ). The each come into action muscles depend heavily on the breathing technique ( chest breathing or abdominal breathing ).

During normal breathing, the muscles play only for the inspiration a role (inhalation). For this purpose, an expansion of the chest is required, the so-called through inspiratory muscles will be realized ("backers"). To produce a higher negative pressure in the pleural space , and thus an extension of the lung , whereby air is sucked. The exhalation takes place is mostly produced passively by slackening the muscles. Because of the elastic fibers in the lung tissue pulls together this and presses the air out of the lungs. Only with increased respiration or lung disease exhalation (must also accessory muscles expiratory "Exspiratoren") are supported.
