What keeps your body working every day?

Think about all the things your body does: Breathing Moving Eating and digesting food Thinking and feeling What makes all of this possible?

Your Body is an Amazing System!

Your body is like a complex machine Made up of 7 major systems working together Each system has a special job All systems must work together to keep you healthy Today we'll explore each system and its function

The Seven Major Body Systems

Support and Movement Systems

{"left":"SKELETAL SYSTEM: Your body's frame - 206 bones that support and protect your organs, like a strong building frame","right":"MUSCULAR SYSTEM: Over 600 muscles that work with bones to help you move, run, jump, and even smile"}

Transport and Gas Exchange Systems

{"left":"CIRCULATORY SYSTEM: Your body's highway system - heart pumps blood through blood vessels to deliver oxygen and nutrients everywhere","right":"RESPIRATORY SYSTEM: Your breathing system - lungs take in oxygen from air and remove carbon dioxide waste"}

Control and Processing Systems

{"left":"NERVOUS SYSTEM: Your body's control center - brain and nerves send messages throughout your body faster than lightning\nDIGESTIVE SYSTEM: Your food processing plant - breaks down food into nutrients your body can use for energy and growth","right":"ENDOCRINE SYSTEM: Your chemical messenger system - uses hormones to control growth, mood, and body processes"}
