Chapter 24.5, Problem 8QC
Summary Introduction
To review:
Influence of ADH on water reabsorption, the parts of nephron and collecting system where ADH acts.
Introduction:
ADH (antidiuretic hormone) is produced via the hypothalamus and is released from the posterior pituitary gland. It is released in response to the decreased blood volume and acts as an agent to reduce the output of urine. Its high secretion results in the release of small amount of concentrated urine. Reabsorption is the process of transfer of substances from tubule filtrate to the blood.
