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

这是一种喉、气支气粘膜急性感染性疾病；比急性会厌炎更常见。

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

经过气和主支气后，病毒最终到达其主要目标细支气。

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

气和初级支气分支平滑肌上，都有β2受体。

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

食和前三级支气都非常宽大，有气软作支撑。

5.Have you tried to intubate her left bronchus?

有没有试过插进左支气？

6.The mainstem bronchi then divide into smaller and smaller bronchi.

支气会反复分支小支气。

7.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致了严重肺出血和支气坏死——或组织死亡。

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

哮喘会影响呼吸系统，尤其是较小气道，例如支气和细支气。机翻

9.] House: Purulent sputum, dyspnea, bronchi bilaterally.

] 房: 脓性痰、呼吸困难、双侧支气。机翻

10.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致支气炎，即气道壁被破坏导致支气永久性扩张。

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

我们对疾病产生免疫力 身体处理感染有其特殊方法。它有一个系统，能够一开始就阻止感染性物质侵袭，然后通过" 记忆" ，它能给身体—个长久免疫力来抵抗来自将来同种入侵者侵袭。

12.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，气一分为二，形左右主支气。你可以把这些肺部分想象一棵倒置树。

13.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，在某些支气中，黏液下层之下还有一层软；这些软可以使支气变硬并且保持开放。

14.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.

一旦麻疹病毒进入一个毫无戒备人粘膜，它很快就会开始感染气或支气上皮细胞。

15.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.

排向腔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病原体。

16.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，延伸为两侧支气。

17.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，空气通过气进入肺部，然后继续穿过支气和细支气，最后进入肺泡。

18.The lower respiratory system begins with the larynx, or voice box, and includes the trachea, or wind pipe, bronchi, bronchioles, and alveoli within the lungs.

下呼吸系统始于喉、也可称音箱，并且包括气，也可称风，支气，细支气和肺肺泡。

19.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体，也就是螺旋形粘液栓，或是本质上是支气哮喘患者小支气塑细长粘液。

20.The trachea is part of the conducting zone, and it branches into right and left primary bronchi, carrying air to and from the right and left lung, respectively.

气是传导区一部分，并且它分支出右和左主支气，它们运载气体进出相应肺。
