(Excretion, micturition, hemodialysis, ureotelic, uricotelic, transport maximum, glomerular filtration rate, osmoregulation, renal threshold, nephron, countercurrent system, ultrafiltration)

.......... is the process of removal of waste products (mainly nitrogenous wastes) from the body.

Answer 1

Excretion is the process of removal of waste products (mainly nitrogenous wastes) from the body.

Through excretion organisms control osmotic pressure—the balance between inorganic ions and water—and maintain acid-base balance. The process thus promotes homeostasis, the constancy of the organism’s internal environment.
