Summary of Osmoregulation
Osmoregulation is the process that keeps body fluid osmolarity at a value of 290 mOsm/L. This process involves osmoreceptors in the anterior hypothalamus and the kidneys. It occurs by negative feedback: when plasma osmolarity increases, due to water deprivation, for example, osmoreceptors are stimulated and there is stimulation of thirst and antidiuretic hormone secretion. Antidiuretic hormone will then decrease plasma osmolarity by making the late distal tubule and collecting ducts reabsorb more water. The opposite happens when plasma osmolarity decreases.
