WebPlasma Osmolality. The plasma osmolality is maintained within narrow limits.3 Small 2% to 3% changes in plasma osmolality are sensed by osmoreceptors located in the hypothalamus, which by stimulating or inhibiting the release of vasopressin, lead to increases or decreases in the excretion of free water. By acting on the baroreceptors, the ... Webin the rats on solid chow; however, plasma sodium concentra-tions and plasma osmolality remained low. Despite mainte-nance of significant hypo-osmolality, rats in which escape was subsequently reversed by water restriction reestablished high dDAVP-stimulated kidney levels of AQP-2 after4dofwater restriction.
