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

所以血液和脏滤液中有五个主要的缓冲剂，身体可以用来缓冲氢离子。

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

滤液离开囊后流入，后者被周毛细血网包。

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

这种再吸收过从球滤液进入循环系统。

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

最终滤液变成尿液，通过输尿从脏排出，进入膀胱，再尿出。

The glomerular filtrate is not the same consistency as urine, as much of it is reabsorbed into the blood as the filtrate passes through the tubules of the nephron.

球滤液与尿液的浓度不同，当滤液通过时，大部分被重新吸收到血液中。

Sometimes fluid or electrolytes can move back from the filtrate into the blood - called reabsorption, and sometimes more fluid or electrolytes can move from the blood to the fitrate - called secretion.

有时液体或电解质能从滤液回到血液中，被称为重吸收；有时更多液体或电解质从血液流入滤液，称之为分泌。

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.

血液通过动脉流入脏，一旦入，便进入一团动脉，即球，开始过滤；滤液过滤出来，进入。

In these situations, the nephron tries to hold on to salt and water, so by the time filtrate has moved into the distal tubule, there's very little of both sodium and water remaining in the lumen.

在这种情况下，单位试图保留盐和，所以当滤过液移入远曲时，只有少量钠和留在腔中。
