Recoil pressure of lungs
WebbThis creates a lower pressure within the lung than that of the atmosphere, causing air to be drawn into the lungs. During expiration, the diaphragm and intercostals relax, causing … WebbPleural pressure is lower than alveolar pressure because of a suction effect caused by fluid removal by the lymphatic system and by lung recoil. As the lungs recoil, the visceral and …

Gas always flows from a higher to a lower pressure. During inspiration, expansion of the thorax causes the intrapleural and alveolar pressures to decrease, gas flows into the lung. During exhalation passive recoil of the lung causes the intrapleural pressure and
