what parts make up the system?
today i found a really good diagram for the excretory system. It is a type of diagram where you roll over the picture to get more information. It shows the main parts of the excretory system and what each part is needed for:
kidneys: cleans the blood of waste products. the waste is removed from the body through urine.
ureter: thin tubes which transport the urine from each kidney to the bladder
bladder: a compartment in the lower part of the body. the bladder is where urine is stored until ready to be disposed.
urethra: urine is transported to the urethra from the bladder, when being excreted.
