On a particularly busy day, a student taking anatomy and physiology i does not have anything to drink from 9: 30 am until 6: 30 pm. osmoreceptors in the brain detect the decreased level of water in the blood. these receptors send a signal to the hypothalamus/posterior pituitary, which stimulates the release of antidiuretic hormone (adh). this hormone acts on the nephron tubules and collecting ducts in the kidney to increase reabsorption of water, which returns that water to the blood. this retention of water has the additional effect of decreasing urinary output. as the fluid levels in the blood stabilize, the release of adh ends.
