- In healthy individuals, water homeostasis is accurately controlled, so that plasma osmolality (Posm) and its principal determinant, plasma sodium (Na) are maintained within a narrow range
- This control is achieved by the close integration of water excretion and water intake
- Water intake governed by -> sensation of thirst, mainly regulated by … Disorders of electrolyte balance 1. Abnormalities in water balance are manifested as sodium disturbances- … Water and sodium balance are closely interdependent.
