1.Elastin gives us the ability to move.

弹性赋予我们移动的能力。

2.In some structures microfibrils form a scaffold for additional proteins like elastin.

在一些结构中，微纤丝为其他提供支架作用，比如说弹性。

3.The tunica externa also has nerve fibers, lymphatic vessels, and in the biggest vessels, the protein elastin.

外膜也有神经纤维、淋巴管，在最大的血管中也有弹性。

4.And that includes molecules in the dermis like elastin and collagen, creating tangled clumps or breaking them down.

而这些分子又包括像真皮中的弹性胶原一类的物质，造成结束或分解。

5.There's also elastin, a protein that gives your skin the ability to bounce back when you stretch it.

一个叫弹性，也是一种质，它可以让皮肤在拉扯后速还原。

6.We have proteins in the skin that are called collagen and elastin, giving structure to aspects in our skin.

我们皮肤中的质被称为胶原弹性，为我们皮肤的各个方面提供结构。

7.My next step is this little elastin restorative skin complex.

我的下一步是使用这种小弹性修复性皮肤复合物。机翻

8.First, the collagen in our folds stiffens and the surrounding elastin fibers atrophy and decay.

首先， 我们褶皱中的胶原变硬，周围的弹性纤维萎缩腐烂。机翻

9.Next there's the tunica media or middle tunic which is mostly made of smooth muscle cells and sheets of elastin protein.

接下来是血管中膜，主要由平滑肌细胞弹性组成。

10.Surrounding the tunica intima is the middle layer, the tunica media, made of smooth muscle cells and sheets of the protein elastin.

围绕内膜的是中间层，中膜，由平滑肌细胞质弹性片组成。

11.These tissues contain elastic proteins like collagen and elastin, which allow them to slightly elongate over the duration of the stretch.

这些组织含有弹性， 如胶原弹性，可以让它们在拉伸期间略微伸长。机翻

12.Reticular tissue is like areolar tissue, but with a woven mess of reticular fibers — rather than collagen and elastin fibers — hence the name.

网状结缔组织类似于蜂窝组织，但是由网状纤维编织而成——而不是胶原弹性纤维——因此得名。

13.So retinoids can help maintain the structure of your dermis and fight off wrinkles by making your body produce more collagen, elastin, and GAGs.

类维生素 A 能促使身体产生更多胶原、弹性糖胺聚糖，从而有助于保真皮结构，抵抗皱纹。

14.Neutrophils make an enzyme called neutrophil elastase, a protease capable of breaking down elastin, which is an extracellular matrix protein that gives elasticity and strength to lung tissues.

中性粒细胞产生中性粒细胞弹性酶，该酶能够水解弹性；弹性是一种细胞外基质，赋予肺组织弹性韧性。

15.So while these little guys can help fight off infection by breaking down proteins of the bacteria, it can also go on to break down that precious elastin.

因此，当这些战士们在水解细菌质击溃感染的同时，也可能会进一步水解十分珍贵的弹性。

16.They're made out of the protein elastin which allows them to stretch and recoil like rubber bands; they're found in places like your skin, lungs, and blood vessel walls.

它们是由质弹性制成的，这使得它们能够像橡皮筋一样伸展后退。它们存在于你的皮肤、肺血管壁中。

17.The aorta and its major branches are elastic arteries — they contain more elastin than any other blood vessel type, so they can absorb the large pressure fluctuations as blood leaves the heart.

主动脉及其主要分支是弹性动脉——它们比任何其他血管类型都含有更多的弹性，因此它们可以吸收血液离开心脏时的巨大压力波动。

18.Nicotine causes narrowing of the blood vessels in the outermost layers of the skin, while the chemicals in tobacco smoke damage collagen and elastin, fibres which give the skin its elasticity.

尼古丁会导致皮肤最外层的血管收缩，而烟雾中的化学物质会损害那些赋予肌肤弹性的胶原弹力。

19.Without alpha-1 antitrypsin, the opposite happens - neutrophil elastase goes unchecked, and it damages the walls of the alveoli, and without that elastin, the alveoli loses its elasticity and structural integrity.

如果没有α-1抗胰酶，情况就会背道而驰：中性粒细胞弹力酶不受抑制，将会损伤肺泡壁，没有了那层弹性纤维，肺泡壁便失去弹性结构完整性。

20.Fortunately, the liver makes alpha-1 antitrypsin which gets released into the blood and sent to the lungs, where it inhibits neutrophil elastase just like it inhibits trypsin, inactivating it before it can break down the protein elastin.

幸运的是，肝产生α-1抗胰酶，释放入血进肺，在肺中像抑制胰酶一样，抑制中性粒细胞弹性酶，使弹性酶在水解弹性纤维之前失活。
