What muscles are involved in inhalation and exhalation?
Inhalation is accomplished when the diaphragm contracts and flattens, moving the floor of the thorax inferiorly, and the intercostal muscles lift the rib cage up and outward. Exhalation is gen- erally a passive event, except in cases of forced exhalation.
What muscles are used in exhalation?
