It is an inflammatory condition of the larynx, trachea and bronchi; more common than acute epiglottitis.

这是一种喉、气管支气管粘膜的急性感染性；急性会厌炎更常见。

Smooth muscle along the trachea and the first few branches of bronchi have beta 2 adrenergic receptors.

气管和初级支气管分支的平滑肌上，都有β2受。

It goes down past the trachea and main bronchi to eventually reach the bronchioles - it's primary target.

经过气管和主支气管后，毒最终到达其主要目标细支气管。

The trachea and the first three generations of bronchi, are all pretty wide and use cartilage rings for support.

食管和前三级支气管都非常宽大，有气管软骨作支撑。

Chronic bacterial infection and inflammation can lead to bronchiectasis, which is airway wall damage causing permanent dilation of the bronchi.

长期细菌感染和炎症可以导支气管炎，即气道壁被破坏导支气管的永久性扩张。

The actions of these cohorts eventually led to severe pulmonary haemorrhage and necrosis – or tissue death – within the bronchi.

这种团伙行动最终导了严重的肺出血和支气管内的坏死——或组织死亡。

Asthma affects the respiratory system, particularly the smaller airways, such as the bronchi and bronchioles.

哮喘会影响呼吸系统，尤其是较小的气道，例如支气管和细支气管。

First comes the trachea and the bronchi.

首先是气管和支气管。

Have you tried to intubate her left bronchus?

有没有试过插管进左支气管？

In the case of asthma, most of the harmful immunological events occur within the bronchi and bronchioles.

在哮喘的情况下，大多数有害的免疫事件发生在支气管和细支气管内。

] House: Purulent sputum, dyspnea, bronchi bilaterally.

] 房: 脓性痰、呼吸困难、双侧支气管。

Others in such high-risk areas as the walls of the bronchi and the intestines remove certain bacteria and shattered cells.

我们对产生免疫力 身处理感染有其特殊的方法。它有一个系统，能够一开始就阻止感染性物质的侵袭，然后通过" 记忆" ，它能给身—个长久的免疫力来抵抗来自将来同种入侵者的侵袭。

Once the measles virus gets onto the mucosa of an unsuspecting person, it quickly starts to infect the epithelial cells in the trachea or bronchi.

一旦麻疹毒进入一个毫无戒备的的粘膜，它很快就会开始感染气管或支气管上皮细胞。

The mainstem bronchi then divide into smaller and smaller bronchi.

支气管会反复分支成小支气管。

Now, once air makes it's way into the larynx, it then continues down as the trachea or the windpipe, which splits into the two mainstem bronchi.

而一旦空气进入咽喉，接下来就是气管，延伸为两侧的支气管。

These are the glands that secrete the majority of the mucus into the lumen of the bronchi, helping to catch and filter out particles and pathogens.

排向管腔的黏液绝大多数由这些黏液腺分泌，这些黏液可以阻挡和过滤微小的原。

From there, the trachea splits in two, forming the right and left main bronchi. You can imagine these inner lung parts as sort of an upside-down tree.

从那里，气管一分为二，形成左右的主支气管。你可以把这些肺内部分想象成一棵倒置的树。

During inhalation, air reaches your lungs by traveling down your trachea, then it continues through the bronchi and the bronchioles and ends up in the alveoli.

吸气时，空气通过气管进入肺部，然后继续穿过支气管和细支气管，最后进入肺泡。

Occasionally in the sputum there might be curschmann spirals, which are spiral shaped mucus plugs or basically elongated mucous casts from small bronchi of people with bronchial asthma.

偶尔在痰中可能会有库什曼螺旋晶，也就是螺旋形的粘液栓，或是本质上是支气管哮喘患者的小支气管塑成的细长粘液。

Finally, in the bronchi, but not the bronchioles, there is also a layer of cartilage below the submucosa which stiffens the bronchus and helps to keep it open.

最后，在某些支气管中，黏液下层之下还有一层软骨；这些软骨可以使支气管变硬并且保持开放。
