Question
Chapter 24.6, Problem 32WDYL
Summary Introduction
To analyze:
The process of establishment and maintenance of the concentration gradient is essential for the normal function of ADH in water reabsorption.
Introduction:
ADH or Anti-diuretic hormone is secreted from the posterior pituitary gland. This hormone is associated with the maintenance of the water balance. Hyposecretion of this hormone leads to a condition called diabetes insipidus which is characterized by increased elimination of urine.
