The excretory system removes liquid waste from the body through two kidneys that filter blood, ureters that transport urine from the kidneys to the urinary bladder, a bladder that stores urine, and a urethra that empties the bladder.

1. The Excretory System
Removes liquid wastes from the body

2. Kidneys
• They are two, one left kidney and one right
kidney.
• They remove wastes from the blood (filters)
blood through nephrons.

5. Ureters
• They are very thin tubes that come out of
each kidney to connect kidneys with the
urinary bladder.
• Urine passes through the ureters to reach the
urinary bladder

7. Urinary Bladder
• It is a sac, that stores urine (till it is time for
you to go to the bathroom).

9. Urethra
• It is an opening in the urinary bladder, where
urine passes when your bladder is full.
