muscular	works with ____ to move the body; helps maintain ____	____<br>__<br>____
nervous	sends ____ to control other systems; communicates with __ and ____	____<br>__<br>____
circulatory	transports ____ and __ to cells; helps remove ____	____<br>__<br>____
respiratory	brings in ____ for the __; removes ____	____<br>__<br>____
digestive	breaks down ____ into __; provides energy for ____	______

Explanation:

To solve this, we recall the functions of each body system:

Skeletal System

• Supports the body and protects organs; works with the muscular system to allow movement.
• Example: The ribcage supports and protects the heart and lungs; bones and muscles work together for arm movement.

Muscular System

• Works with the skeletal system to move the body; helps maintain posture.
• Example: Biceps (muscle) and humerus (bone) work to lift a weight; muscles keep the spine aligned.

Nervous System

• Sends signals to control other systems; communicates with sensory organs and the brain.
• Example: Nerves signal muscles to contract; eyes (sensory) send info to the brain.

Circulatory System

• Transports oxygen and nutrients to cells; helps remove waste (like CO₂).
• Example: Blood carries O₂ from lungs to muscles; removes CO₂ from cells.

Respiratory System

• Brings in oxygen for the body; removes carbon dioxide.
• Example: Lungs take in O₂; exhale CO₂ after gas exchange.

Digestive System

• Breaks down food into nutrients; provides energy for cells.
• Example: Stomach digests food; nutrients (glucose) fuel brain cells.

Body System	How It Helps Other Systems	Example of Interaction
Muscular	Works with skeletal system to move the body; helps maintain posture	Biceps + humerus lift weights; muscles keep spine aligned
Nervous	Sends signals to control other systems; communicates with sensory organs and brain	Nerves signal muscles to contract; eyes send info to the brain
Circulatory	Transports oxygen and nutrients to cells; helps remove waste (CO₂)	Blood carries O₂ to muscles; removes CO₂ from cells
Respiratory	Brings in oxygen for the body; removes carbon dioxide	Lungs take in O₂; exhale CO₂ after gas exchange
Digestive	Breaks down food into nutrients; provides energy for cells	Stomach digests food; glucose (nutrient) fuels brain cells

Answer:

(Key Blanks):

• Skeletal: body, muscular system
• Muscular: skeletal system, posture
• Nervous: signals, sensory organs, brain
• Circulatory: oxygen, nutrients, waste (CO₂)
• Respiratory: oxygen, body, carbon dioxide
