The Excretory system

The excretory system consists of the bladder, the ureter, the urethra, and the kidneys. After food is digested, it comes out of the stomach and into the bladder through a tube called the ureter. The stomach acid goes into the kidneys. The kidneys are like a storage room. The bladder is a storage room for urine,a.k.a. pee. When the bladder is full, a.k.a. when you need to go, the urine comes out of the body through another tube called the urethra. Then, it starts all over again.
