The bladder is able to expand and contract because it's wrapped in a muscular layer, called the detrusor muscle, and within that, lining the bladder itself is a layer of transitional epithelium containing " umbrella cells" .

膀胱既可以扩张也可以收缩，因为膀胱壁有一层肌肉，叫做逼尿肌，而且膀胱内衬有一层由“伞状细胞”（盖细胞）组成的变移上皮。

The only cells it really infects are what we call respiratory epithelial cells, a one-cell layer of cells that kind of protect the breathing tubes and the lungs, all the way down to the bottom, where we have air sacs.

唯一真正受感染的细胞是我们所说的呼吸上皮细胞，一种保护呼吸和肺的单细胞层，一直底部有气囊的地方。

To start, the bacteria will have to get breathed in, slip by your nose hairs, past the cilia in the airways, and will then have to penetrate past the epithelium layer of the lungs.

首先，细菌得吸入从鼻毛过，经过呼吸的纤毛，然后得穿过肺的上皮细胞层。

In the bronchioles you've got the lumen, the mucosa which includes the inner lining of epithelial cells as well as the lamina propria, and the submucosa which is where the smooth muscle lives.

在细支气内，有腔体、粘膜（包括上皮细胞的内层、固有层），以及粘膜下层，也就是平肌所在的地方。

From your stomach on down, though, the inner GI tract is lined with simple columnar epithelial cells, which secrete all sorts of stuff, and which absorb and process various nutrients.

然而，从你的胃开始，内侧胃肠排列着简单的柱状上皮细胞，它们泌各种东西，吸收和处理各种营养。

That odor-filled air heads right up your nasal passages in your nose where the odor molecules are finally trapped by a thin bit of tissue called olfactory epithelium.

充满气味的空气会直接进入你的鼻腔，在那里气味称为嗅觉上皮的薄组织捕获。

The second most common cause is called Conn syndrome and this is where an adenoma or tumor in the glandular epithelial cells secretes too much hormone.

第二常见的原因称为Conn综合征：这是由于起源于腺上皮细胞的腺瘤或肿瘤泌过多的激素。

They theorised that, in the absence of worms, the inflamed epithelial tissues in normal mice might instead identify the egg-white protein as an intruder.

他们推测，在没有蠕虫的情况下，正常小白鼠体内发炎的上皮组织可能会将蛋清蛋白识别为入侵者。

She heard the splash of hooves behind her and moved farther over on the narrow sidewalk to avoid more mud splotches on Aunt Pittypat's cloak.

她听背后马蹄趟水的声音，便在狭窄的人行上更往里靠一点，免得让更多的污泥溅上皮蒂姑妈的那件外套。

So its mucosa is made up of stratified squamous epithelium, which is better equipped to resist abrasion from food going down.

因此，其粘膜是由复层鳞状上皮构成的，能较好地抵御食物对食的磨损。

During a yeast infection, discharge may become thicker and whiter because the vagina is shedding more epithelial and Candida cells.

在酵母菌感染期间，由于阴脱落更多的上皮细胞和念珠菌细胞，泌物可能会变稠变白。

These are little bones that come off the nose, they're called turbinates, lined with specialized sensory epithelium.

这些是从鼻上脱落的小骨头，它们称为鼻甲，布有专门的感觉上皮。

The CPE specifically targets the tight junctions that connect epithelial cells lining the intestines to one another.

毒素（CPE）作用于肠上皮细胞之间的紧密连接。

They're incorporated into the epithelial cells lining Elysia's digestive system that branches throughout its flat body.

它们整合绿叶海天牛消化系统的上皮细胞中，并广泛布在它扁平的身体上。

You run and hide from the monsters that want to peel the skin from your bones.

你跑着，躲着那些想剥掉你骨头上皮的怪物。

In a very similar way, the membranes covering your lungs for example, are actually invaginations of your epithelium — where the tissue that makes up your you-tube folds to form a cavity — just like this balloon when I push my fingers into it.

打个比方，覆盖在你肺部的薄膜实际上是上皮的内陷——构成你的输卵的组织折叠形成一个腔——就像我把手指伸进去的这个气球。

When the virus comes in contact with the respiratory mucosa or the skin of a new person, it starts replicating in the epithelial cells.

病毒进入新感染者的呼吸粘膜或皮肤，随即开始了在上皮细胞中的复制。

It's a normal hyperplastic response, meaning the epithelial cells in the area divide more than usual and build up a protective layer of keratin.

这是一种正常的增生反应，与通常情况下相比，该部位裂出了更多的上皮细胞，以构筑起一个角质保护层。

When Ashley went into the cold to see the boys off to the depot in Aunt Pitty's carriage, Melanie caught Scarlett's arm.

当艾希礼出门送几个小伙坐上皮蒂姑妈的马车车站去时，媚兰抓住思嘉的胳臂唠叨起来。

The other way epithelial cells can necrose is via nephrotoxins, which are substances that tend to damage the epithelial tubular cells.

另一种上皮细胞坏死的方式是由于肾毒素，这些物质往往损坏肾小上皮细胞。
