va·so·pres·sin

 (vā′zō-prĕs′ĭn)
n.
A hormone secreted by the posterior lobe of the pituitary gland that constricts blood vessels, raises blood pressure, and reduces excretion of urine. A synthetic form of the hormone is used as an antidiuretic drug, especially in the treatment of diabetes insipidus. Also called antidiuretic hormone.

vasopressin

(ˌveɪzəʊˈprɛsɪn)
n
(Biochemistry) a polypeptide hormone secreted by the posterior lobe of the pituitary gland. It increases the reabsorption of water by the kidney tubules and increases blood pressure by constricting the arteries. Also called: antidiuretic hormone Chemical name: beta-hypophamine Compare oxytocin

(ˌvæs oʊˈprɛs ɪn)

n.
a hormone released by the posterior pituitary gland that constricts small blood vessels and increases the absorption of water by the kidney. Also called antidiuretic hormone, ADH.

It was thought that the changes in ruminal fluid osmolality were sensed by the osmoreceptors in the rumen wall and these signals were then transported to the central nervous system (Leek and Harding, 1975).
Osmoreceptors in the patient's hypthalamus stimulated posterior pituitary gland vasopressors to release antidiuretic hormone to increase blood pressure through the renal tubules retaining water.
Osmoreceptors in her hypothalamus stimulated posterior pituitary gland vasopressors to release antidiuretic hormone, in order to increase blood pressure by the renal tubules retaining water (Gutierrez, Reines & Wulf-Gutierrez, 2004).
If you get too little liquid, it's going to shrink your cells, and osmoreceptors in your brain and other parts of your body are going to sense that cells need water.
Osmoreceptors in the hypothalamus and heart/blood vessel baroreceptors detect changes in plasma concentrations, producing or reducing anti-diuretic hormone (ADH) concentrations to increase, or decrease water absorption respectively (von Duvillard, 2004).
It appears as though the osmoreceptors are 'reset' at a lower level to avoid a continuous diuresis.
