Filtering is done by hair-like cellular appendages called cilia.

清除由像头发一样称为纤细胞附属器官完成。

Around this time, many former smokers notice a decrease in the frequency of lung infections because the healed cilia can do their job more easily.

大约这个时候，许多戒烟者注意到肺部感染频率降低了，因为治愈纤可以更容易地完成它们工作。

At the top of each hair bundle, as you can see in this image, there's a fine filament connecting each of the little hairs, the stereocilia.

这张图里能看到，每一簇束顶上，都有一根纤细丝，把每根叫做静纤纤连接起来。

Tiny hairs inside your nose called cilia help push it further down your nose.

你鼻子里叫做纤发帮助把它推到鼻子下面。

But the team did see single-celled organisms called ciliates in the sick urchins.

但该调查组确实患病海胆中发现了名为纤虫单细胞生物。

This duct is full of tiny microvilli called stereocilia, which provide a huge surface area to help reabsorb some extra fluid, and help pass along nutrients to feed the idling sperm.

这条管道充满了被称为立体纤微绒，它提供了一个巨大表面积来帮助重新吸收一些额外液体，并帮助传递营养来喂养空转精子。

As a result of having too much mucus and poorly functioning cilia, people with chronic bronchitis end up relying on coughing to get rid of their mucus plugs.

因为有太多痰液集聚，纤功能也变差，慢支病患者只能靠咳嗽来排除阻塞痰液。

These cells are referred to as hair cells because very small bundles of stereocilia, which look like hairs under a microscope, sit on top of each cell.

这些细胞之所以被称为细胞，是因为显微镜下看起来像发非常纤束位于每个细胞顶部。

Histologically, a prominent feature are their perivascular pseudorosettes, which are ring-like structures formed by tumors cells with rod-shaped ependymal processes, like cilia, surrounding a centralized blood vessel.

从组织上看，主要特征是血管周假菊形团，由室管膜瘤细胞棒状突起（如纤）形成环状结构，围绕着中央血管。

These guys can transform into ciliated columnar cells, so they help regenerate and replace damaged ciliated columnar epithelial cells if needed.

它们可以转化为纤柱状上皮细胞，必要时可以替代和修复受损纤柱状上皮细胞。

In 3-9 months, the damaged cilia in the lungs are almost fully repaired, which are hair-like structures that helps sweep away dust and debris.

3至9个月后 肺部受损纤几乎完全被修复了，纤是帮助清除肺部灰尘和碎片类发结构。

It does this by damaging the cilia, tiny hairlike structures whose job it is to keep the airways clean.

它是通过破坏纤来实现，微发状结构，其作用是保持气道清洁。

The delicate, hair-like structures inside the lungs known as cilia, which help to fight infections, will have recovered from the toll of cigarette smoke.

肺部纤是一种纤细发状结构，有助于抵抗感染，它这个时候会从香烟伤害中恢复过来。

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，细菌得被吸入从鼻滑过，经过呼吸道纤，然后得穿过肺上皮细胞层。

For example, we have mechanical techniques like coughing, a mucociliary escalator that lines the entire airway and moves out larger bacteria, and macrophages that are nestled deep inside the alveoli and ready to destroy anything that lands there.

例如，我们有像咳嗽这样技能，贴气道黏膜纤可移除较大细菌，而巨噬细胞则肺泡深处准备吞噬降解那里东西。

These special nerve cells are covered in cilia, which are like tiny hairs that stick out and trap the smell particles as they float past.

这些特殊神经细胞被纤覆盖，纤就像细发一样伸出来，气味颗粒飘过时将它们困住。

On the inside, the fallopian tubes have smooth muscle with an inner lining that has ciliated cells that slowly sweep the secondary oocyte or zygote towards the uterus.

输卵管内是有纤细胞覆盖平滑肌，这些纤可以缓慢地将次级卵母细胞或者受精卵向子宫运输。

Stentor coeruleus is a part of a group called the ciliates.

Stentor coeruleus 是纤虫群一部分。

The lung organoids, for example, had working lung cilia—hairlike structures that rhythmically beat to clear mucus and debris—just like the real thing.

例如，肺类器官具有正常工作肺纤——有节奏地跳动以清除粘液和碎屑发状结构——就像真实东西一样。

And they have little cilia, little hair or microvilli that is literally like little hair that is exposed to the lumen.

它们有微纤，类似细发或微绒，直接暴露管腔内。
