Both bones have an alveolus, or socket, for each tooth.

它们都富有凹槽即牙槽，以放置牙齿。

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。

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

在肺里，管包绕着半球状囊泡，即肺泡。

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

由于肺泡负责气交换，这可不是好消息。

The first part is the root, and it sits within the alveolus.

第一部分是牙根，位于牙槽骨内。

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

肺气肿是指肺中被为肺泡的微小结构破裂。

Men have some breast tissue as well, but they lack milk secreting alveoli.

男性也有乳房组织，但他们没有分泌乳汁的腺泡。

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

身也试图通过咳嗽，使那脱离肺泡。

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

当这积聚起来后，就会使肺泡内的空气转换更加困难。

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

在健康的宝宝内，肺泡就像一个个充满了气的微型气球一样。

And with each breath in, oxygen enters the alveoli and freely diffuses into the blood.

而每次呼吸，氧气都会进入肺泡，通过自由扩散进入。

And pneumonia, often triggered by bacterial or viral infections, attacks the alveoli themselves.

肺炎——常常由菌或病毒感染引发——会攻击肺泡本身。

These outpouchings are called alveoli, and there are about 500 million of them within the lungs.

这突起为肺泡，在肺部大约有5亿个肺泡。

But some of these invaders may get past the mucociliary escalator into the lungs, where they meet the alveoli.

但是有入侵者有可能通过粘膜纤自动扶梯并进入到肺里，并接触到肺泡。

Pneumonia is an infection of the alveoli that causes them to fill with fluid.

肺炎是一种肺泡感染，会导致肺泡充满。

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

这代表着肺泡中充满了，从而在CT显像中呈现灰色阴影。

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

一旦足量积充斥着肺部管，可能会出现破溃，渗出进入肺泡。

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，菌毒素会破坏肺泡管内膜，从而导致肺泡内出。

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

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

The immune system releases additional white blood cells in the alveoli to help.

免疫系统也会在肺泡中释放出更多的白胞去帮忙。
