Human Excretory System Definitions:
Many system have evolved for excreting waste that are simpler than the kidney and urinary system of vertebrate animals.

Removal of excretory products is called excretion.

Human Excretory System Notes:
The process is involved in the removal of waste material, products of metabolism, toxic materials as well as substances, in excess of requirement. For instance, human cannot digest cellulose in their food that directly goes through the alimentary canal, and taken out of the anus in the faeces. Further more, the product cellulose is not taken as excretory material, so it couldn't be participated in metabolic reaction in person's cells. kidney plays an important function in excretion of urine formation, which is the final liquid made by the kidneys, is a solution of urea and salts in water. Urine flows out of the kidneys, with the help of ureters and into the bladder.
