Excretory System:

Excretory system has 4 parts:

Kidney : They are the main organ of the excretory system because they filter the harmful substances from the blood. They have kidney beans like structure.

Ureters : When the kidney filters the waste they dissolve in water to produce urine and then it passes through ureters.

Urinary bladder : After passing, it reaches to the urinary bladder and stored there.

Urethra : And then urine passes through urethra.
