The image represents the image of labelled human excretory system.
The human excretory system includes organs that facilitate the removal of nitrogenous wastes from the body. The main excretory organs include kidney, ureter, urinary bladder and urethra. Kidneys filter the blood and urine is the filtrate obtained. Urine passes to the urinary bladder via ureter and is expelled out of the body. This is known as micturition. Kidneys also regulate the osmotic pressure of a mammal’s blood through excessive purification and filtration. This is known as osmoregulation.
The human excretory system organs include:
A pair of kidneys
