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

滤离开肾小囊后流入肾小管，后者被管周毛细血管网包围。

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滤进入循系统。

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

最终滤变成尿，输尿管从肾脏排出，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.

肾小球滤尿的浓度不同，当滤肾小管时，大部分被重新吸收到血中。

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.

有时体或电解质能从滤回到血中，被称为重吸收；有时更多体或电解质从血流入滤，称之为分泌。

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，肾单位试图保留盐和水，所以当滤移入远曲小管时，只有少量钠和水留在管腔中。
