1. The physiological processes by which organisms maintain the balance of water and dissolved salts (osmotic pressure) in their body fluids.
Usage: Usually used in plural or as a mass noun in biological contexts; Technical term in biology and physiology

Examples

• Fish rely on osmoregulations to maintain proper salt and water balance in freshwater and saltwater environments.
• The kidneys play a crucial role in osmoregulations by filtering excess water and salts from the blood.
• Marine organisms have evolved specialized osmoregulations to cope with high salinity levels.
• Osmoregulations in desert animals allow them to conserve water and survive in arid conditions.
• Students learned about osmoregulations in their biology class when studying how cells maintain homeostasis.
