2.74 ADH

ADH - Anti Diurectic Hormone

Produced in the Brain (specifically the hypothalamus area) and through the blood stream it gets carried to the Kidney.

ADH - control or alters the quantity of water in the blood

The collecting Duct - part of the Nephron. Where the ADH works

It is possible to incease the amount of water re-absrobed back into the blood, by applying ADH.
ADH makes the collecting ducts walls more porous so that more water can escape.

As a consequence: urine is more concentrated and in lower volume 

Summary: With ADH secretion, more water goes back into the blood, but urine becomes more concentrated with lower volume as well
