Expiration is gas flow out.) ... In quiet expiration, why are no muscles required to contract? Quiet expiration is a passive process, in which the diaphragm and the external intercostal muscles. relax, and the elastic lungs and thoracic wall recoil inward.
What happens during quiet exhalation?
During quiet breathing, the diaphragm and external intercostals must contract. A deep breath, called diaphragmatic breathing, requires the diaphragm to contract. As the diaphragm relaxes, air passively leaves the lungs. A shallow breath, called costal breathing, requires contraction of the intercostal muscles.
How is quiet expiration produced?
Quiet respiration depends on elastic recoil of the lungs after inspiratory stretching, elastic recoil of the costal cartilages, and the relaxation of the inspiratory muscles. As the inspiratory muscles relax, the volume of the thoracic cage decreases by elastic recoil of the costal cartilages, and the lungs recoil.
