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。

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

由于肺泡负责换，这可不好消息。

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

肺炎——常常由细菌或病毒感染引发——会攻击肺泡本身。

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。

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囊。

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

肺肿指肺中被称为肺泡的微小结构破裂。

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的微型球一样。

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

这些突起称为肺泡，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.

但有些入侵者有可能通过粘膜动扶梯并进入到肺里，并接触到肺泡。

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。

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

第一部分牙根，位于牙槽骨内。

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。

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，叫做肺泡的微小囊中，肺泡将二氧化碳转化为氧的部位。

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

而每次呼吸，氧都会进入肺泡，通过由扩散进入血液。

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，细菌毒素会破坏肺泡细血管内膜，从而导致肺泡内出血。

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

在肺里，细血管包绕着半球状囊泡，即肺泡。

This allows air to be drawn in, inflating the alveoli — millions of small sacs inside our lungs.

于空被吸进来，充满肺泡——肺泡我们肺部成千上万的小囊。

Both of your lungs contain about 700 million alveoli, which together provide an amazing 75 square meters of moist membrane surface area.

你的两个肺包含大约 7 亿肺泡，它们共同提供了惊人的 75 平方米的湿膜表面积。

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液，从而在CT显像中呈现灰色阴影。

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血细胞去帮忙。
