WebOsmoregulation. Osmoregulation is the process of maintaining salt and water balance ( osmotic balance) across membranes within the body. The fluids inside and surrounding cells are composed of water, electrolytes, and nonelectrolytes. An electrolyte is a compound that dissociates into ions when dissolved in water. WebTonicity is a bit different from osmolarity because it takes into account both relative solute concentrations and the cell membrane’s permeability to those solutes. Three terms—hypertonic, hypotonic, and isotonic—are used to …
