The excretory system is the group of organs that get rid of cell wastes. 

 Kidneys are the most important organs in this system.  Kidneys are about the size of a fist.  Blood with cell wastes goes into your kidneys through arteries.  On the inside of your kidneys the blood flows through small blood vessels until it reaches the capillaries.  Wastes from blood goes through thin walls in a capillary into very little tubes.  The tubes take away some salts, nitrogen wastes, and extra water from the blood.  Your kidneys forty times a day.   The wastes form a liquid called urine.

The kidneys are like a very complicated set of filters.
