Lesson Transcript
Instructor: Rebecca Gillaspy

Dr. Gillaspy has taught health science at University of Phoenix and Ashford University and has a degree from Palmer College of Chiropractic.

The excretory system is in charge of getting rid of wastes and extra water in the body. It's made up of your kidneys, ureters, bladder, and urethra. Read on to learn more about the excretory system and how it cleans your blood to keep you healthy.

What Is the Excretory System?

Your body needs water to survive. If you went more than a couple of days without water, you would be very thirsty and your cells would not be able to keep functioning. But not all water is okay to drink. Before you fill up your glass, the water must be filtered to remove impurities that could hurt you.

Your body has a similar filtering system called the excretory system. The excretory system filters the blood to remove wastes that could be harmful to the body.

There are four main parts that make up the excretory system: the kidneys, ureters, bladder, and urethra. Let's explore!

Kidneys

Your kidneys are the blood filters. They are responsible for removing wastes and extra water that your body doesn't need from your blood. Imagine if you drank four large lemonades in a row and had no way of getting rid of all that extra fluid. You'd slosh around when you move! It's a good thing your kidneys remove that extra liquid.

You have two kidneys. They're shaped like large beans and sit toward your back, near the bottom of your rib cage. All of the blood in your body travels through your kidneys to get cleaned. Your kidneys decide what should stay in your blood, like nutrients, and what should leave your body, like extra water and urea. Urea is a waste produced by your cells.
