Find out the various organs in the body that aid in eliminating metabolic wastes. Can you label the parts of it?

Guide Card2Direction: Arrange the jumbled letters to form the name of the organ that helps in eliminating waste.

1. YEDNKI two bean-shaped organs that filter blood to produce the urine.2. SREURTE tubes that lead from each kidney to the bladder.3. REDLADB a bag-shaped muscular organ that stores urine until it leaves the body through the urethra.4. REUARTH a tube leading from the bladder to the outside of the body.5. MEGLOLUSRU tiny filtering units in the body.
