Quantitative and direct studies of microcirculatory fluid exchange phenomena provide evidence that fluid tissue balance in omentum and mesentery is achieved through lymphatic drainage. Fluid exchange in muscle appears to alternate between filtration and absorption from the capillaries in synchrony with arteriolar vasomotion. Detailed calculations show that, in the absence of hydraulic or osmotic pumping at the level of the terminal lymphatics, tissue pressures are of the order of +6 cm H2O for both visceral and muscle tissue. It is concluded that these microcirculatory beds represent two extreme types of mechanisms for achieving fluid balance, and that most other tissues, with the exception of liver and tumors, operate in between.
对微循环液体交换现象的定量和直接研究表明,网膜和肠系膜中的液体组织平衡是通过淋巴引流实现的。肌肉中的液体交换似乎与小动脉血管运动同步,在毛细血管的滤过和吸收之间交替进行。详细计算表明,在终末淋巴管水平不存在液压或渗透泵的情况下,内脏和肌肉组织的组织压力约为+6厘米水柱。得出的结论是,这些微循环床代表了实现液体平衡的两种极端机制类型,并且除了肝脏和肿瘤之外,大多数其他组织在两者之间运作。
