Pulmonary surfactant - Wikipedia

WebFigure 22.3.1 – Boyle’s Law: In a gas, pressure increases as volume decreases. Pulmonary ventilation is dependent on three types of pressure: atmospheric, intra-alveolar, and interpleural. Atmospheric pressure is the amount of force that is exerted by gases in the air surrounding any given surface, such as the body. WebSep 19, 2024 · This results in surface tension limiting the compliance of lung tissue. Surface tension refers to the tendency of fluid to shrink to the smallest possible volume. In water, the pull of hydrogen bonds between molecules generates surface tension. Fluid lines the alveolar surface, thus resisting stretching of the alveoli. The higher the surface ... Webemphysema/COPD may be associated with an increase in pulmonary compliance due to the loss of alveolar and elastic tissue. Pulmonary surfactant increases compliance by decreasing the surface tension of water. The internal surface of the alveolus is covered with a thin coat of fluid. The water in this fluid has a high surface tension, and ... ins check my case
