These substances caused capillaries to become leaky, so fluid leaks out, causing extracellular edema that further increases intra-compartment pressure.

这些物质会使毛细通透性增高，体液外渗引起细胞外水肿，进一步加重了腔室内压力。

When the lungs are affected, the toxins damage the alveolar-capillary membranes, which can result in bleeding within the alveoli.

A common cause of increased hydrostatic pressure in the lung capillaries is heart failure.

肺毛细内静水压升高常见原因是心力衰竭。

Finally, there's capillary permeability or leakiness which affects how easily fluid is actually able to get through.

最后一个因素是毛细通透性，反映液体通过毛细膜难易程度。

The high pressure forces fluid out of the capillaries and into the pleural space.

高压促使液体流出毛细，进入胸膜腔。

They may be little, but your capillaries are where the big, important exchange of materials actually happens.
