What does the heart do?
The heart is a muscle that pumps blood filled with oxygen to all parts of your body. This job keeps every cell, organ, and system alive within your body.

The delivery system moves blood from the heart carrying oxygen and nutrients throughout your body and also picks up waste products so that your body can get rid of them.
What do the kidneys do?
Your kidneys are two bean-shaped organs and are usually about the size of your fist. They are located a little below your rib cage and to the left and right of your spine. Your kidneys are powerful chemical factories and have the following jobs:
- Clean your blood of waste products and extra water
- Help control blood pressure
- Keep bones healthy and strong
- Help make red blood cells
