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

它可以阻止吞噬体和溶酶体融合，从而在肺泡巨噬细胞内生存并增殖。

Also known as the alveolar approximant sound that we find in words like red, car, and sorry.

称为齿槽接近音，我们在 red，car 和 sorry等词中能找到这个音。

Alveolar macrophages then eat up these red blood cells, which causes them to take on this brownish color from iron build-up.

肺泡巨噬细胞之后会吞噬这些红细胞，导致这些细胞由于铁元素积聚而呈现棕褐色。

The alveolar walls are made of extremely thin, flat cells that are surrounded by capillaries.

肺泡壁由极薄且扁平的细胞构成，这些细胞被毛细血所环绕。

So, bring you tongue tip to your alveolar ridge.

所以，将舌尖带到牙槽嵴上。

The English alveolar approximant, the Spanish trill, the French uvular fricative?

英国的齿槽音、西班牙的颤音、法国的小舌擦音？

Together, the alveolar wall and capillaries make a two-cell-thick membrane that brings blood and oxygen close enough for diffusion.

肺泡壁与毛细血共同构成了一层仅两细胞厚的膜，使血液与氧气紧密接触，便于扩。

As you can see below, small capillaries press up against the respiratory zone, bringing the blood close to the alveolar air.

正如你在下面所看到的，小毛细血挤压着紧贴呼吸区，携带血液紧靠肺泡气。

As blood flows through the pulmonary capillaries, oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar gas.

当血液流过肺毛细血时，氧气扩到血液中，二氧化碳扩到肺泡气体中。

Bacterial growth and death of alveolar macrophages produce powerful chemotactic factors that cause a large influx of polymorphonuclear leukocytes and monocytes from the peripheral blood.

军团菌的增长及肺泡巨噬细胞的死亡产生了强大的趋化因子，造成大量多形核白细胞和单核细胞从外周血涌入。

The respiratory membrane separates the alveolar air on one side from the blood on the other.

呼吸膜将一侧的肺泡空气与另一侧的血液分离。

This respiratory surface, also known as the respiratory membrane, includes the alveolar epithelial cells as well as the pulmonary capillary endothelial cells.

呼吸表面，称为呼吸膜，包括肺泡上皮细胞和肺毛细血内皮细胞。

Eventually the respiratory bronchioles ends when there are nothing but alveoli, and at that point the airway is called an alveolar duct rather than a respiratory bronchiole.

最终呼吸性细支气结束于肺泡，此时气道被称为肺泡，而不是呼吸性细支气。

They're all produced with the tongue near to or actually touching that ridge behind the upper teeth, which is technically called the alveolar ridge.

它们都是通过将舌头靠近或实际上触及上牙后方的齿龈脊发出的，这一部位在语音上被称为齿龈脊。

Now, it's not clear whether it's a uvula or an alveolar trill, or just a stronger sound that's more familiar in North America today.

现在， 尚不清楚这是一种小舌音， 还是一种齿龈颤音，或者仅仅是比今天北美更常见的更强烈的发音。

The partial pressure of oxygen is 100 mmHg in alveolar air compared to only 40 mmHg in the blood entering the lungs.

肺泡空气中的氧分压为100 mmHg，而进入肺部的血液中只有40 mmHg。

So the alveolar wall, the basement membrane, and the capillary wall is really all that separates the air from the blood, and this is called the blood-gas barrier.

所以，肺泡壁、基底膜和毛细血壁将空气和血液分离，这个结构叫气血屏障。

The partial pressure of carbon dioxide is 40 mmHg in the alveolar air and 45 mmHg in the blood entering the lungs.

肺泡空气中的二氧化碳分压为40 mmHg，进入肺部的血液中的二氧化碳分压为45 mmHg。

The respiratory membrane is very thin, as it consists of only two cells - that is, the alveolar epithelial cell and the pulmonary capillary cell.

呼吸膜很薄，因为它只有两个细胞，即肺泡上皮细胞和肺毛细血细胞。

As you can see in the picture above, the partial pressure of carbon dioxide in the alveolar air is about 40 mmHg.

如上图所示，肺泡空气中二氧化碳的分压约为40 mmHg。
