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

肺部受累时，细菌毒素破坏肺泡毛细血管内膜，从而导致肺泡内出血。

The body also tries to force the fluid out of the alveoli through coughing.

身也试图通过咳嗽，使那些液脱离肺泡。

As alveoli are responsible for gas exchange, this is not good news.

由于肺泡负责气交换，可不是好消息。

At the end of each branch is a tiny air sac called an alveolus.

在每个分支的末端都有一个叫做肺泡的小气囊。

Emphysema is when the tiny structures in your lungs called alveoli, break down.

肺气肿是指肺中被称为肺泡的小结构破裂。

When this fluid builds up, it makes gas exchange inside the alveoli much more difficult.

当些液积聚起来，使肺泡内的空气转换更加困难。

This makes the walls look thicker, like white lines against the hazy, ground glass background.

肺泡壁增厚，像一条条白线将模糊的磨玻璃影分裂开。

It has the ability to stop phagolysosomal fusion, and survive and replicate inside alveolar macrophages.

它可以阻止吞噬和溶酶融合，从而在肺泡巨噬细胞内存并增殖。

That problem happens deep in the lungs, in tiny air sacs called alveoli, which exchange carbon dioxide for oxygen.

个问题出现在肺部深处，叫做肺泡的小气囊中，肺泡是将二氧化碳转化为氧气的部位。

In the lungs, the capillary lines up alongside a small sack of air called an alveolus.

在肺里，毛细血管包绕着半球状囊泡，即肺泡。

Free from particles, the inhaled air is now in the alveolus surrounded by mostly type I pneumocytes.

移出异物，肺泡中的空气周围围绕的大多是I型肺泡细胞。

In healthy babies, the alveoli are like perfectly inflated mini-balloons.

在健康的宝宝内，肺泡像一个个充满了气的型气球一样。

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，可能出现破溃，血液渗出进入肺泡。

They represent tiny air-sacs or alveoli getting filled with fluid, and turning a shade of grey on CT scans.

代表着肺泡中充满了液，从而在CT显像中呈现灰色阴影。

Initially, doctors had no way to alter the stretchability or squeeziness of their patients' air sacs.

最初，医没有办法改变病人肺泡的拉伸性或挤压力度。

This is where the blood vessels and alveoli start filling with excess fluid.

此时血管和肺泡开始充满多余液。

And if there's one thing your body hates, it's a bunch of exotic material spicing up your sensitive alveoli!

如果有你身讨厌的东西进来的话，是一堆有毒的东西让你的肺泡激动起来了！

They represent tiny air-sacs or alveoli getting filled with fluid, and turning a shade of grey on a CT scan.
