Quick Recall Flashcards

What is ADH and what does it do?

ADH (antidiuretic hormone) is released by the pituitary gland. It makes the kidneys reabsorb more water from the filtrate back into the blood, producing smaller amounts of more concentrated urine.

What is osmoregulation?

Osmoregulation is the control of the water content and ion concentration of the blood. The kidneys are the main organs responsible for this.
