Explain human excretory system.

1.	Explain human excretory system.
Answer» The excretory system of human beings consists of the following main organs: two kidneys, two ureters, bladder and urethra. Kidneys are located in the abdomen, one on either side of the backbone. Urine produced in the kidneys passes through the ureters into the urinary bladder where it is stored until it is released through the urethra.\xa0The process of removal of toxic waste from the body of an organism is called excretion. The excretory unit of a kidney is called nephron. The excretory system removes the poisonous waste substances from the body in the form of urine and maintains ionic balance called osmoregulation.
