An exudative pleural effusions is due to inflammation of the pulmonary capillaries which makes them much more leaky.

渗出性胸腔积肺毛细血管发炎，变得更易漏出。

Pleural effusions can be due to excess fluid collection, transudative and exudative, or due to blockage of lymphatic drainage.

胸腔积由于体形成过快，分漏出性胸与渗出性胸，或者由于淋巴引流阻塞，体吸收过缓。

Transudative fluid looks clear, exudative effusions are full of immune cells and therefore look cloudy, and lymphatic fluid is filled with fats and looks like milk.

漏出透明清亮；渗出有许多炎性细胞，此看起来混浊；淋巴充满脂肪，所以看起来像牛奶。

Often, the biggest challenge is distinguishing between a transudative and exudative effusion, and the key difference is the amount of protein in the effusion - exudates have much more!

而最大的挑战经常辨别漏出与渗出，关键的不同点体的蛋白质总量：渗出中的含量更多！
