Question
Chapter 40, Problem 7SQ
Summary Introduction
Introduction: Hormone is important to regulate the urine’s concentration and its composition. Hypothalamus gland signals the pituitary gland to release antidiuretic hormone (ADH). ADH is a hormone that increases the reabsorption of the water through passive transport protein called aquaporins.
