The urinary system is a group of organs that work together to make and remove urine from your body. Think of it as your body's waste disposal system for liquids!
Urine is a watery waste product. Your body needs to get rid of this waste to stay healthy. The main organs that make urine are your two kidneys. They clean your blood by filtering out waste.

What Organs Make Up the Urinary System?
The urinary system includes four main parts:
How Does Your Urinary System Work?
Your urinary system is always busy cleaning your blood and getting rid of liquid waste. Here's how it works step-by-step:
How Do Kidneys Clean Your Blood?
Your kidneys are like amazing filters. They remove waste chemicals, such as urea, from your blood. Blood with these waste chemicals enters your kidneys through special tubes called renal arteries. Inside each kidney, tiny filtering units called nephrons clean the blood. This process creates urine, which is yellow water filled with waste chemicals.
Where Does Urine Go After the Kidneys?
Once the urine is made, it travels from your kidneys down to your urinary bladder. It moves through two thin tubes, one from each kidney. These tubes are called ureters.
What Does the Bladder Do?
The urinary bladder is a soft, stretchy bag that holds urine. It has strong muscles that allow it to get bigger as it fills up. When your bladder is full, you start to feel the need to pee.
How Does Urine Leave the Body?
When you're ready to pee, the urine leaves your bladder through one final tube. This tube is called the urethra. It carries the urine out of your body.
