With this test, tuberculin is injected between layers of the dermis.

在这个试验中，结核菌素注射于两层真。

With less structural support from the dermis, your skin starts to look thinner and build up wrinkles.

你的肤也因真层功能的衰退显得更薄，并且产生皱纹。

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中的弹性蛋白和胶原一类的物质，造成结束或分解。

At any given time, up to 25% of the body's blood is circulating through the dermis, making this process extremely efficient.

在任何时，超过25%的身血液通过真循环。这使得调节温这个过程非常有效。

You can expect even more damage to the lower layer of your skin, AKA the dermis.

你的肤下层，也就是真层，可能会受到更多的损伤。

The epidermis is supported by the dermis, which is where you'll find nerve endings, sweat glands, hair follicles, and connective tissue.

表由真层支撑，在真层中有神经末梢、汗腺、毛囊和结缔组。

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 能促使身产生更多胶原、弹性蛋白和糖胺聚糖，从而有助于保护真结构，抵抗皱纹。

Some of the ink particles are also suspended in the gel-like matrix of the dermis, while others are engulfed by dermal cells called fibroblasts.

有些颜料颗粒悬浮在胶质的真结构中，而其它颜料颗粒被叫做成纤维细胞的真细胞吞噬。

The needles punch through the epidermis, allowing ink to seep deep into the dermis, which is composed of collagen fibers, nerves, glands, blood vessels and more.

针刺透表让颜料深入真，真下是胶原纤维、神经、腺、血管等等。

Made up of three layers, the epidermis, dermis, and hypodermis, skin's thickness varies from 0.5 millimeters at its thinnest and up to four millimeters at its thickest.

表层，真层和下组。肤最薄处为0.5mm，最厚处为4mm。

These microbes, which include bacteria and fungi, thrive in the sebum, an oily substance that's secreted onto the skin's surface by sebaceous glands nestled inside the dermis.

包括细菌和真菌的这些微生物，在脂内十分活跃，也就是由紧贴在真内的脂腺分泌到肤表面的油性物质。

As these cells travel through the lymphatic system, some of them are carried back with a belly full of dye into the lymph nodes while others remain in the dermis.

当这些细胞在淋巴系统中运动，有一部分携带着大量颜料进入淋巴结，另外一些依然留在表下。

That proboscis though keeps going into the dermis, since the epidermis just gets oxygen from the air and doesn’t have its own blood supply, whereas the dermis does, and this is what our mosquito’s after, right, the blood meal.

但蚊子的喙一直刺入真，因为表只是从空气中获取氧气，不像真有血液供应；这就是蚊子的目标：血液大餐。
