Antidiuretic hormone (ADH) a. increases water reabsorption in the kidneys. b. regulates blood pressure by constricting arterioles. c. decreases the volume of urine produced by the kidneys. d. probably arose from the same ancestral gene as that of oxytocin. e. does all of the above.
Antidiuretic hormone (ADH), a large peptide hormone, is produced by the hypothalamus in the brain, and is released into the bloodstream when necessary to regulate water and electrolyte balance. Upon binding to its receptor, it activates a G-protein coupled receptor signal transduction cascade. ADH is best described as a ____ hormone, and acts on cells in the collecting duct to ___. A. paracrine; increase electrolyte reabsorption B. neuroendocrine; decrease water reabsorption C. paracrine; decrease water reabsorption D. neuroendocrine; increase electrolyte reabsorption E. neuroendocrine; increase water reabsorption
Antidiuretic hormone (ADH) a. increases water reabsorption in the kidneys. b. regulates blood pressure by constricting arterioles. c. decreases the volume of urine produced by the kidneys. d. increases blood pressure during times of high blood loss. e. does all of the above.
