NUTRITION: EXCRETORY SYSTEM

 Our excretory system helps us to eliminate waste products. It has different parts:

1. The KIDNEYS clean the blood and turn waste substances into urine.

2. The urine goes down the URETERS, which are long and thin tubes, into the bladder.

3. The BLADDER is like a bag and it holds urine.

 4. Finally, the urine goes down the URETHRA, which is a short tube, and ends up into the toilet.
