📌 What Is A Body System?
- A body system is a group of parts (like organs) that work together to do a special job in your body.
- Just like a team, each system has its own job, but they all help the body work properly.
- For example: Your digestive system breaks down food, your heart pumps blood, and your lungs help you breathe.
📌 Why Are Body Systems Important?
- All body systems work together to keep you healthy and strong.
- Your lungs help you breathe, your heart pumps blood, and your brain tells your body what to do.
- It’s like a sports team, everyone has a role so the team can win!.
