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: -Kidneys regulate the osmotic pressure of a mammal’s blood through extensive filtration and purification, in a process known as osmoregulation. Kidneys filter the blood; urine is the filtrate that eliminates waste from the body via the ureter into the bladder.
Detailed explanation-3: -The biological or technical term for the process of maintaining water and salt balance in the blood is known as osmoregulation. Osmoregulation helps in maintaining homeostasis of the body.
Detailed explanation-4: -Osmoregulation is a homeostatic mechanism that regulates the optimum temperature of water and salts in the tissues and body fluids. It maintains the internal environment of the body through water and ionic concentration.
Detailed explanation-5: -The kidney is the main organ responsible for osmoregulation in humans. Water, amino acids and glucose are reabsorbed by the kidneys. When the water level in the body is high, it releases a large amount of hypotonic urine. When the water level is low, it retains water and produces a low amount of hypertonic urine.
