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

清除由像头发一样的称为纤的细胞附属器官完成。

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的频率降低了，因为治愈的纤可以更容易地完成们的工作。

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，每一簇束的顶上，都有一根纤细的丝，把每根叫做静纤的小纤来。

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

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

但该调查小组确实患病的海胆中发现了名为纤虫的单细胞生物。

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的微，提供了一个巨大的表面积来帮助重新吸收一些额外的液体，并帮助传递营养来喂养空转的精子。

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，纤的功能也变差，慢支病患者只能靠咳嗽来排除阻塞的痰液。

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，是因为显微镜下看来像发的非常小的纤束位于每个细胞的顶部。

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.

从组织学上看，主要的特征是血管周假菊形团，由室管膜瘤细胞的棒状突（如纤）形成的环状结构，围绕着中央的血管。

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

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的纤柱状上皮细胞。

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 肺部受损的纤几乎完全被修复了，纤是帮助清除肺部灰尘和碎片的类发结构。

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

是通过破坏纤来实现的，微小的发状结构，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.

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

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，经过呼吸道的纤，然后得穿过肺的上皮细胞层。

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，我们有像咳嗽这样的技能，贴气道的黏膜纤可移除较大的细菌，而巨噬细胞则肺泡深处准备吞噬降解那里的东西。

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.

这些特殊的神经细胞被纤覆盖，纤就像细小的发一样伸出来，气味颗粒飘过时将们困住。

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的平滑肌，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 是纤虫群的一部分。

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的肺纤——有节奏地跳动以清除粘液和碎屑的发状结构——就像真实的东西一样。

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

们有微小的纤，类似细小的发或微，直暴露管腔内。
