Your body is made of systems that each do a different job. The digestive system breaks down food so your body can use it. The circulatory system pumps blood around your body. The respiratory system, with your lungs, lets you breathe.
| System | Job |
|---|---|
| Digestive system | Breaks down food |
| Circulatory system | Pumps blood |
| Respiratory system | Helps you breathe |
| Excretory system | Removes waste |
These systems work together every second. The food you eat is broken down, its nutrients travel in your blood, and waste leaves your body. Cherishing a clean, neat body every day supports all these systems.
