And then there's a luge, which is one person with a shorter little tube or sled, is the correct word, and they just do it by time.

然后有一个雪橇，这是一个人短的小管或雪橇，是的，正确的话，他只是按时间排名。

Really, though, you're much more likely to experience pain in response to cold or hot things which contract or expand the fluid in those tubules than you are in response to sugar.

不过，和对糖的反应相比，你更有可能在对冷或热的东西作出反应时体验到疼痛，这些东西会导致这些小管中的液体收缩或膨胀。

So as a quick recap, intrarenal AKI is kidney injury caused by something within the kidneys themselves, which could be the tubules as in acute tubular necrosis, the glomerulus as in glomerulonephritis, or the interstitium as in acute interstitial nephritis.

好！快速回顾一下：急伤是由脏内部引起的急伤，可能是小管，如急小管坏死；或小球，如小球炎；或间质，如急间质炎。

This is an ingenious retractor which is only five millimeters, and we can stick down the little tubes that can go safely in the abdomen.

这是一个巧妙的牵开器，只有 5 毫，可以插入小管，可以安全地进入腹部。

These tubules are important for sensory nerves as well, which use them to travel through the dentin from the pulp to the dentin-enamel junction.

牙本质中的小管对感觉神经也很重要，因为感觉神经可以通过它从牙髓到达本釉质交界处。

All this twisting might make the tubule look, like, super inefficient, but it actually serves an important purpose, as you might expect.

所有这些扭曲可能会让小管看起来超级低效，但它实际上有一个重要的目的，正如你所料。

These tubes though also allow fluids and electrolytes to move through the tube walls and back into the blood if needed.

如果身体需要，这些小管同时也允许部分水和电解质穿过管壁回到血液循环中。

Cells have small tubes that assemble to help with cell division and DNA replication, then break back down.

细胞具有组装在一起的小管以帮助细胞分裂和DNA复制，然后分解。

Usually, tau proteins support tiny tubes inside our axons called microtubules.

通常，tau蛋白要支撑称为微管即存在于轴突中的小管。

If your enamel is worn away, your dentin and its tubules can be exposed.

如果你的牙釉质被磨掉了，你的牙本质和它的小管就会暴露出来。

And this sperm-making work is supported by cells throughout and around the tubules.

这种精子制造工作是由遍布小管及其周围的细胞支持的。

These tubes focus almost exclusively on reabsorbing water back into the blood.

这部分小管最主要的作用就是重吸收水入血。

Sometimes the cells and the surrounding inflammatory protein debris is even " casted" into the shape of the tubule which is then also peed out and is called a white blood cell cast.

有时可见细胞和周围炎蛋白碎片，有的甚至形成“小管”形状，称为白细胞管型，也会随尿液排出。

The odontoblasts have long processes, or arms, that lay within tiny tubules in the dentin - like an octopus sticking it's arms through a block of cement.

成牙质细胞有长长的突起，或者说长臂，伸入牙本质中的小管，就像章鱼的触角伸进水泥块被困住一样。

And this meandering path also allows the parts of the tubule that are toward the end, to have an affect on processes that take place closer to the beginning, as they pass each other.

这条蜿蜒的路径也允许小管接近末端的部分，当它相互传递时，对发生在更接近开始的过程产生影响。

ADH affects the last two-thirds of these tubes, called the distal convoluted tubule and the collecting ducts.

ADH作用于这些小管的终末2/3部分，即远曲小管和集合管。

It contains microscopic, fluid-filled tubules that run from the pulp to the underside of the enamel.

它包含微小的、充满液体的小管，从牙髓一直到牙釉质下层。

The targets of the testosterone are the outermost cells in the tubules, called spermatogonia.

睾酮的目标是小管中最外层的细胞，称为精原细胞。

It's called a cast because it stays in essentially the same cylindrical shape as the tubule.

它被称为管型，是因为它基本上与小管保持相同的圆柱形状。

These tubules are the sperm factories, made of a stratified epithelium surrounding a central fluid-filled lumen.

这些小管是精子工厂，由围绕充满液体的中央管腔的分层上皮组成。
