The urinary system removes waste from the body through the kidneys, ureters, bladder, and urethra. The kidneys filter waste from the blood to produce urine, which travels through the ureters to the bladder. The bladder stores urine until it is released through the urethra. The urinary system works with other body systems like the circulatory, nervous, and muscular systems to effectively regulate fluids and expel waste from the body.

2.  The urinary system removes wastes products
from our body.
 The body takes nutrients from food and
makes it into energy. Then the body takes the
food that it needs, and the waste goes into
the blood.

3.  Kidneys: organs that filter waste from the blood and produce
urine.

 Ureters: thin tubes that take pee from the kidney into the bladder.

 Bladder: a sack that holds pee until you go to the bathroom.

 Urethra: a tube that carries urine from the bladder out the body
when you pee.

 Sphincter Muscles: Sphincter muscles are two circular muscles
around the opening of the bladder into the urethra. They help
keep urine from leaking into the urethra.

5.  Endocrine system: A chemical substance that allows
the kidneys to effectively regulate fluids in the body.
 Circulatory system: Processes of cleansing the blood
of waste, removing excess fluids and generally
keeping other fluids in balance.
 Nervous system: Bladder is a muscle that can expand
and contract as necessary to accommodate or expel
urine. When the bladder is full, the nervous system
receives messages that it is time to go…

6.  Muscular and skeletal system: regulate the release of
urine
 Digestive System: releases waste from the digestion.
