Detailed explanation-3: -Excretion is the process by which the body eliminates waste products and the nitrogenous by-products of metabolism. Through excretion, organisms control osmotic pressure, the balance between inorganic ions and water, and maintain acid-base balance. The process thus promotes homeostasis.

Detailed explanation-4: -The system that removes metabolic waste products from the body is the excretory system. This system is in charge of filtering the blood and removing these wastes, then excreting them out of the body. The main organs of the excretory system are the kidneys, the ureter, the bladder and the urethra.
