• A. the hormone produced by the hypothalamus and secreted by the adenohypophysis that promotes reabsorption of water from the glomerular filtrate.
• B. the hormone produced by the hypothalamus and secreted by the neurohypophysis that promotes reabsorption of water from the glomerular filtrate.
• C. the hormone produced and secreted by the hypothalamus that promotes reabsorption of water from the glomerular filtrate.
• D. the hormone produced and secreted by the neurohypophysis that promotes reabsorption of water from the glomerular filtrate.

Answer 1

Answer: (B)

ADH: Antidiuretic hormone - vasopressin is secreted by neurohypophysis (posterior lobe) of the pituitary gland. This hormone increases the reabsorption of water from the urine and hence urine gets concentrated and ECF gets diluted. Diabetes insipidus is caused by the hyposecretion of ADH.
