The excretory system


THE EXCRETORY SYSTEM

ü     The KIDNEYS clean the blood and make urine.
ü     Urine goes down two thin tubes called URETERS into the bladder.
ü     The BLADDER, which is like a bag, holds the urine.

ü     Finally, urine goes down the URETHRA and leaves our bodies when we go to the toilet.
