Each of these tiny balloons is surrounded by a mesh of blood-filled capillaries.

每个这样的小球都被充满血液的网状细血管包围着。

This pull is aided by a fundamental property of water called capillary action.

这种拉力还得到水的一种基本特征——细作用的帮助。

But the tiny blood vessels just beneath your skin called capillaries break.

但是你皮肤下面的细血管破裂了。

Through the capillaries, they reach larger blood vessels and exit the bone.

通过细血管，它们可以抵达更大的血管，离开。

These new cells enter the bloodstream through holes in small capillaries in the marrow.

这些新细胞通过髓里小细血管上的洞进入血液循环。

Some trackers use optical scanners to see the blood actually pumping through your capillaries.

有些追踪器使用光学扫描仪来观察血液流过细血管的情况。

Instead the glomerulus funnels blood into efferent arterioles which divide into capillaries a second time.

而是由肾小球将血液输送进入出球小动脉，后者分支复成细血管网。

Lymphatic capillaries are the smallest lymphatic vessels, and they're located throughout the interstitial space.

细淋巴管是最小的淋巴管，它们广泛分布于间质。

The pseudotracheae secrete enzyme-filled saliva and soak up fluids and dissolved foods by capillary action.

拟气管通过细管作用来分泌充满酶的唾液渗入它们的食物。

This capillary motion is in full effect in xylem filaments thinner than human hair.

在木质纤维中细作用无处不在，这些木质纤维比人的发还细。

But like the hormones, these are too large to move across capillaries.

但是和激素一样，它们太大以至于不能通过细血管。

Your tiniest capillaries are to you, what the pipes bringing water to homes are to Lisbon.

你身上最细小的细血管之于你，就如同自来水管之于里斯本。

Most arteries and veins connect through a bed of very thin capillaries that bring nutrients and oxygen to cells.

大多数动脉和静脉通过非常薄细血管床连接，而该血管床将营养和氧气带到细胞中。

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

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

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

肺细血管内静水压升高的常见原因是心力衰竭。

Now, I just seal this capillary by putting it in clay.

我只是把它放在粘土中来密封这个细管。

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

高压促使液体流出细血管，进入胸膜腔。

The walls of these capillaries are very thin, and capillaries are very plentiful.

这些细血管的壁很薄，细血管非常丰富。

If enough fluid fills some of these capillaries in the lungs, they can rupture, leaking blood into the alveoli.

一旦足量积液充斥着肺部细血管，可能会出现破溃，血液渗出进入肺泡。

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

最后一个因素是细血管通透性，反映液体通过细血管膜的难易程度。
