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毛细血管包围着。

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

这些新细胞通过骨髓里小毛细血管上的洞进入血液循环。

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

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毛细血管的情况。

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

但是你皮肤下面的毛细血管破裂了。

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

肺毛细血管内静水压升高的常见原因是心力衰。

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——毛细作用的帮助。

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

你身上最细小的毛细血管之于你，就如同自来水管之于里斯本。

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

毛细淋巴管是最小的淋巴管，它们广泛分布于间质。

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

它们可能很小，但是你的毛细血管是大规模的、重要的物质交换真正发生的地方。

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

在木质纤维中毛细作用无处不在，这些木质纤维比人的发还细。

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。

And the endothelium of these capillaries is very porous.

这些毛细血管的内皮细胞多孔性很强。

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毛细血管床连接，而该血管床将营养和氧气带到细胞中。

As they enter the kidneys, renal arteries branch many, many times, ending in tons of little capillary groups.

当它们进入肾脏时，肾动脉多次分支，以成吨的小毛细血管群结束。

Unlike arteries and veins, capillaries don't operate on their own, but rather form interweaving groups called capillary beds.

与动脉和静脉不同，毛细血管不是自己运作的，而是形成交织的群体，称为毛细血管床。

As the filtrate leaves the Bowman's capsule it flows into the renal tubule, which is surrounded by the peritubular capillaries.

滤液离开肾小囊后流入肾小管，后者被管周毛细血管网包围。

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

拟气管通过毛细管作用来分泌充满酶的唾液渗入它们的食物。

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血管通透性，反映液体通过毛细血管膜的难易程度。

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毛细血管，可能会出现破溃，血液渗出进入肺泡。
