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泡的小气囊。

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

在，细血管包绕着半球状囊泡，即泡。

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

由于泡负责气交换，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.

气肿是指中被为泡的微小结构破裂。

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，使那些液脱离泡。

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

当这些液起来后，就会使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，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，氧气都会进入泡，通过自由扩散进入血液。

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

炎——常常由细菌或病毒感染引发——会攻击泡本身。

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

这些突起为泡，在部大约有5亿个泡。

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

但是有些入侵者有可能通过粘膜纤自动扶梯并进入到，并接触到泡。

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

炎是一种泡感染，会导致泡充满液。

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

这代表着泡中充满了液，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.

一旦足量液充斥着部细血管，可能会出现破溃，血液渗出进入泡。

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

部受累时，细菌毒素会破坏泡细血管内膜，从而导致泡内出血。

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

这个问题出现在部深处，叫做泡的微小气囊中，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.

免疫系统也会在泡中释放出更多的白血细胞去帮忙。
