Detailed explanation-1: -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.

Detailed explanation-2: -Osmoregulation is the control of water levels and mineral ions (salt) in the blood. Water levels and mineral ions in the blood are controlled to keep the concentrations the same inside the cells as around them. This protects cells by stopping too much water from entering or leaving them by osmosis.

Detailed explanation-3: -osmoregulation, in biology, maintenance by an organism of an internal balance between water and dissolved materials regardless of environmental conditions.

Detailed explanation-4: -Osmoregulation is under the control of a single hormonal system, ADH, whereas volume regulation is under the control of a set of redundant and overlapping control mechanisms. Lack or excess of ADH results in defined and rather dramatic clinical syndromes of excess water loss or water retention.

Detailed explanation-5: -Osmoregulation refers to the physiological processes that maintain a fixed concentration of cell membrane-impermeable molecules and ions in the fluid that surrounds cells.
