Receptors that help to control water intake by responding to the concentrations of bodily fluids. See also volume receptors.

Peripheral sensory receptors sensing the osmotic pressure, for example in stomach or small intestine.

Hypothesized cells in the hypothalamus that respond to dehydration by stimulating the release of ADH by the pituitary gland, which, in turn, signals the kidneys to reabsorb water into the bloodstream. See also antidiuretic hormone, volumetric receptors.
