WebThe regulation of breathing is dependent on the complex interaction of three components of the respiratory system: 1) the control centers, 2) the sensors, and 3) the effector … WebSurface tension forces at the air–water interface in the alveoli significantly impact pulmonary mechanics and function. By lowering and varying surface tension during breathing, lung surfactant reduces the work of breathing, stabilizes alveolar inflation/deflation behavior, reduces edema formation, and facilitates gas exchange.

Normal respiratory physiology works as a negative pressure system. When the diaphragm pushes down during inspiration, negative pressure in the pleural cavity is generated, this, in turn, creates negative pressure in the airways that suck air into the lungs.
