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。

Some substances are removed from blood through the peritubular capillary network into the distal convoluted tubule or collecting duct.

有些物质通过管周毛细血管网从血液中移出，进入远曲小管或集合管。

So when ADH is low, most of the water flows through the the distal convoluted tubule and the collecting duct, giving us diluted urine.

所以当血中ADH水平低时，大部分水就顺着远曲小管和集合管排出体外，尿液也就被稀释。

And at this point the distal tubule and collecting ducts of the nephron can either reabsorb or secrete potassium depending on what the body needs.

这时，远曲小管和肾单位导管会根据需要重吸收或者分泌钾离子。

That leaves 13% of the initial amount, and at this point the distal tubule and collecting ducts of the nephron can either reabsorb or secrete potassium depending on what the body needs.

余下原始量的13%，此时肾单位的远曲小管和集合管，依据机体的需要，或重吸收，或分泌出钾。
