Explain in short about five organs of the human excretory system.

Organs of the human excretory system include the Skin, Liver, Large Intestine, Lungs, and Kidneys.

1.Skin 

It is the largest organ of a human body. 

Its primary function is to protect the different organs of the body, along with excretion of compounds like NaCl and some amount of urea, through the production of sweat by sweat glands in the dermis.

2.Liver

It plays an important role in excreting waste from the body. 

It regulates most chemical levels in the blood and excretes a product called bile.

It converts poisonous ammonia into urea and is excreted from the urine.

3.Large Intestine

Its main function is to eliminate solid wastes that remain after the food is digested. 

It also collects and excretes waste from throughout the body, including bilirubin (a waste product from the liver), in the bile.

4.Lungs

It is responsible for the excretion of gaseous wastes from the body. 

The main waste gas that is excreted by the lungs is carbon dioxide, which is produced by cellular respiration in cells throughout the body

5.Kidneys

It is the main organ of the human excretory system. 

Its primary function is to eliminate excess water and wastes from the bloodstream by the production of urine. 

It is part of the urinary system, which includes the ureters, urinary bladder, and urethra. These are organs that transport, store, and eliminate urine, respectively.
