Let’s go step by step to fill in the table for each body system shown in the diagrams.
We have 6 diagrams from left to right. Let’s identify each one:
---
Diagram 1 (leftmost):
Shows bones — skull, ribs, spine, arms, legs → This is the
Skeletal System.
- Function: Supports the body, protects organs, helps with movement.
- Main organ involved: Bones (like femur, skull, ribs)
---
Diagram 2:
Shows brain and spinal cord with nerves going out → This is the
Nervous System.
- Function: Controls body activities, sends messages between brain and body.
- Main organ involved: Brain, spinal cord, nerves
---
Diagram 3:
Shows heart and blood vessels (red and blue lines) → This is the
Circulatory System (also called Cardiovascular System).
- Function: Transports blood, oxygen, nutrients, and waste around the body.
- Main organ involved: Heart, blood vessels
---
Diagram 4:
Shows lungs and airways → This is the
Respiratory System.
- Function: Takes in oxygen and removes carbon dioxide.
- Main organ involved: Lungs, trachea, bronchi
---
Diagram 5:
Shows stomach, intestines, liver → This is the
Digestive System.
- Function: Breaks down food, absorbs nutrients, removes waste.
- Main organ involved: Stomach, intestines, liver
---
Diagram 6 (rightmost):
Shows muscles all over the body → This is the
Muscular System.
- Function: Helps move the body, keeps posture, generates heat.
- Main organ involved: Muscles (like biceps, quadriceps)
---
Now let’s put this into the table format as requested.
Final Answer:
| Diagram | Body system | Function | Main organ involved |
|---------|--------------------|-----------------------------------------------|----------------------------------|
| 1 | Skeletal System | Supports body, protects organs, aids movement | Bones |
| 2 | Nervous System | Controls body, sends signals | Brain, spinal cord, nerves |
| 3 | Circulatory System | Transports blood, oxygen, nutrients | Heart, blood vessels |
| 4 | Respiratory System | Takes in oxygen, removes CO₂ | Lungs, trachea |
| 5 | Digestive System | Breaks down food, absorbs nutrients | Stomach, intestines, liver |
| 6 | Muscular System | Moves body, maintains posture | Muscles |
Parent Tip: Review the logic above to help your child master the concept of body systems and functions worksheet.
