As the filtrate leaves the Bowman's capsule it flows into the renal tubule, which is surrounded by the peritubular capillaries.

离开肾小囊后流入肾小管，后者被管周毛细血管网包围。

So the bladder is able to hold that filtrate.

所以膀胱能够储存那个。

So it moves into the filtrate.

所以它进入。

So now it moves through the filtrate.

于是现在它通移动。

So there's five main buffers in the blood and in the kidney filtrate that the body can use to buffer hydrogen ions.

所以血和肾脏中有五个主要的缓冲剂，身体可以用来缓冲氢离子。

Ultimately the filtrate is turned into urine and is excreted from the kidney through the ureter, into the bladder, and peed away.

最终变成尿，通输尿管从肾脏排出，进入膀胱，再尿出。

Like lining the bottom of landfills with a thick plastic shield so leachate doesn't leak into our water.

就像在填埋场底部铺设厚厚的塑料屏蔽层，以防止渗漏到我们的水源中。

This reabsorption process allows water to pass from the glomerular filtrate back into the circulatory system.

这种再吸收程使水从肾小球进入循环系统。

Now that filtrate will eventually move into the ureter.

现在最终会进入输尿管。

Unless we find ways to stop it, leachate can sink into the drinking water we get from the ground.

除非我们找到方法阻止，否则渗可能会渗透到我们从地下获取的饮用水中。

So in the final steps, after the filtrate leaves the DCT, it enters the collecting duct, which runs back into the medulla.

所以在最后一步，离开 DCT 后，进入收集管，收集管又回到髓质。

Because we're going to have all of this filtrate that's being produced but it has not place to go.

因为我们将产生大量的，但它们无处可去。

Plus, if all that garbage isn't buried right, rainwater can mix with the garbage causing a gooey substance called leachate to form.

此外， 如果垃圾没有正确填埋，雨水会与垃圾混合， 形成一种称为渗的黏糊状物质。

As we move out of the loop of Henle, into the distal convoluted tubule, and on to the collecting duct, the remaining filtrate is now officially urine.

当我们离开亨利氏袢，进入远端卷曲的小管，到达收集管时，剩余的现在正式成为尿。

The remaining filtrate passes from the PCT into the loop of Henle, which starts in the cortex, then dips into the medulla before coming back into the cortex.

剩余的从 PCT 进入 亨利氏袢，从皮层开始，然后浸入髓质，然后返回皮层。

They use it to ramp up the concentration gradient earlier in the process, making the medulla even saltier for the filtrate that's back there going through the ascending limb.

在这个程的早期，他们用它来提高浓度梯度，使髓质对穿上升肢体的更咸。

Now, all the stuff that get squeezed out of the blood into the glomerulus is called filtrate, which is then sent along to the elaborately twisting three-centimeter-long renal tubule.

现在，所有从血中挤出进入肾小球的物质被称为，然后被送到精心扭曲的三厘米长肾小管。

These cells also are covered in microvilli that increase their surface area and help re-absorb much of the good stuff from the filtrate and back into the blood.

这些细胞也被微绒毛覆盖，增加了它们的表面积，有助于从中重新吸收大部分有益物质并回到血中。

Blood gets into the kidney through the renal artery, into tiny clumps of arterioles called glomeruli where it's initially filtered, with the filtrate, the stuff filtered out, moving into the renal tubule.

血通肾动脉流入肾脏，一旦入肾，便进入一小团小动脉，即肾小球，开始；出来，进入肾小管。

But here's a problem: Your kidneys can only handle so much filtrate at a time, so they have to maintain a constant rate of flow inside of them.

你的肾脏一次只能处理这么多，所以它们必须保持体内恒定的流速。
