• the body fluid osmolarity is decreasing.
• Body fluid osmolarity is regulated by renal control of water retention or excretion mediated by the mechanisms described above, and by control of water ingestion by the thirst mechanism.
• Body fluid osmolarity is very tightly regulated by the hypothalamus-posterior pituitary-kidney system and can also be conveniently assumed to be constant, as can ionic strength.
• Body fluid osmolarity is regulated by antidiuretic hormone, related from the posterior pituitary, acting to control water readsorption by the kidneys .
• Body-fluid osmolarity is normally maintained by the hypothalamus-pituitary-kidney team at a value close to 0.
