Detailed explanation-1: -Osmoregulation is help to maintain and balance the water content in our body. Our body requires a constant input of water and electrolytes, but excess amounts of water and electrolytes are excreted from our body with the help of the kidney. Thus, osmoregulation helps to maintain the osmotic balance of our body.

Detailed explanation-2: -osmoregulation is the homeostatic regulation of osmotic pressure in the body in order to maintain a constant water content. excretion in amoeba takes place through its skin .the left over waste is thrown out of body. Excretion means the removal of water substances produced in body due to metabolic activities.

Detailed explanation-3: -To maintain homeostasis, the excretion of water and electrolytes must match an individual’s intake. The kidneys play a substantial role in osmoregulation by controlling the quantity of fluid reabsorbed from the glomerular filtrate.

Detailed explanation-4: -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-5: -Excretion is the process of elimination of such wastes to maintain homeostasis. The kidneys, lungs, liver, and skin expel wastes like water, urea, uric acid, CO 2, salts etc. and hence perform as excretory organs in man.
