Inspiration and Expiration Breathing consists of 2 phases: Inspiration: flow of gases into lungs Expiration: flow of gases out of lungs Inspiration and expiration: Mechanical processes caused by contraction of respiratory muscles Cause volume changes in thoracic cavity Volume changes lead to gas ...
The processes of inspiration and expiration are vital for providing oxygen to tissues and removing carbon dioxide from the body. Inspiration occurs via contraction of muscles such as the diaphragm whereas expiration tends to be passive at rest.
During restful breathing, the diaphragm provides the force for expansion, while expiration is passive and requires no muscles. The external intercostals aid inspiration. The abdominal muscles and internal intercostals aid forceful expiration. Muscles move the chest wall and not the lungs, but the ...
Mechanics of breathing during exercise in men and women: sex versus body size differences? 来自 国家科技图书文献中心 喜欢 0 阅读量: 14 作者:AW Sheel,JA Guenette 摘要: Women have smaller airways and lung volumes and lower resting maximal expiratory flow rates relative to men. Female athletes ...
Inspiration occurs when the inspiratory muscles—that is, the diaphragm and the external intercostal muscles—contract. Contraction of the diaphragm (the skeletal muscle below the lungs) causes an increase in the size of the thoracic cavity, while contraction of the external intercostal muscles elevate...

Forced Oscillation Technique data were interpreted using the mean respiratory impedance (Zt), the impedance during inspiration (Zi), expiration (Ze), at the beginning of inspiration (Zii), and at expiration (Zie). The peak-to-peak impedance (Zpp) was also calculated by the subtraction of Zii...
These measurements can be used to derive a variety of indices, such as volume, compliance, resistance, and work of breathing. Plateau pressure is an indicator of the pressure at the end of the inspiration. More and more researchers are realizing that end-inspiratory transpulmonary pressure (...
