Fluid mechanics in lungs
WebMay 12, 2024 · The outside of the lungs are lined with a membrane called the visceral pleura. The space between these membranes, the pleural cavity or pleural space, is filled with pleural fluid (figure 2.5). Normally there is only 5–10 mL of pleural fluid to cover all the lung’s external surface. So the fluid layer and the intra-pleural space is extremely thin.

WebDec 8, 2024 · As the lungs perform their task of taking in oxygen and expelling carbon dioxide, fluid can accumulate in air sacs of certain patients. The fluid can make it harder for the lungs to perform that gas exchange, and at worst it can bring oxygenation levels low enough to cause death. Webthere are gaseous fluid mechanics, physical diffusion, gas-to-liquid mass transport, muscular movement, and neural integration to consider. Although it can be argued that ...
Pulmonary edema is a condition caused by too much fluid in the lungs. This fluid collects in the many air sacs in the lungs, making it difficult to breathe.
