Excretory System

After food goes through the digestive system, the parts that are not digested need to be gotten rid of. That is the job of the excretory system.

Unabsorbed food goes to the large intestine. The liver also filters out solid particles of waste from the blood. These solid wastes are removed from the body through the rectum, which is at the end of the large intestine.

Liquid wastes are filtered by the kidneys, a part of the excretory system. The kidneys have long tubes coming out of them called ureters that drain liquid into the bladder. The bladder stores liquid waste called urine until it is passed out of the body through the urethra.
