Pharmacotherapy of the Respiratory Muscle
The respiratory system consists of a gas-exchanging organ, the lungs and a pump that ventilates them. The pump consists of the chest wall, which includes the rib cage, the respiratory muscles, and the respiratory centers in the central nervous system which control the diaphragm and the muscles used to expand the chest wall during breathing. The pump is the working or active part of the respiratory system, the lungs being merely passively inflated when the respiratory muscles contracts. The pump is just as vital as the heart, since without it, the lungs would obviously be unable to function, and arterial blood gas homeostasis would not be maintained.
