12 Body Systems Worksheet — Hopscotch - Free Printable

I'll solve this matching exercise by carefully analyzing each question and finding the correct body system.

Let me work through each one:

Question 1: "This provides structure to the human body and protects vital organs."
- The skeletal system provides structure (bones) and protects organs (rib cage protects heart/lungs, skull protects brain)
- Answer: K. Skeletal system

Question 2: "It is also known as the cardiovascular system and carries nutrients and oxygen throughout the body."
- Cardiovascular = circulatory system (heart and blood vessels)
- Answer: F. Circulatory system

Question 3: "Cleans your blood & makes pee."
- The kidneys filter blood and produce urine
- This is the renal/urinary system
- Answer: I. Renal (or Urinary) System

Question 4: "This system includes the body's largest organ, the skin."
- The integumentary system includes skin, hair, nails
- Answer: E. Integumentary system

Question 5: "It is the system that supports the body's movement."
- Muscles enable movement
- Answer: G. Muscular System

Question 6: "This system helps the body turn food into energy and removes excess water, toxins, and waste."
- Digestive system breaks down food; excretory removes waste
- Answer: D. Digestive & Excretory system

Question 7: "It is the system that sends neural signals"
- Nervous system sends electrical signals through nerves
- Answer: J. Nervous system

Question 8: "It is the system that makes hormones"
- Endocrine system produces hormones
- Answer: B. Endocrine system

Question 9: "It is the system that fights off disease"
- Immune system defends against pathogens
- Answer: L. Immune system

Question 10: "It is the system of organs and glands that controls the body's chemical messages through hormones"
- This describes the endocrine system again (glands releasing hormones)
- Answer: B. Endocrine system

Wait, let me reconsider. Looking at the options again... Question 8 asks about making hormones, and Question 10 asks about controlling chemical messages through hormones. Both seem to be endocrine. Let me check if there's a better match for #10. Actually, both are describing the endocrine system in different ways. But I need unique answers. Let me re-examine...

Actually, looking more carefully:
- Q8: "makes hormones" - could be endocrine
- Q10: "controls chemical messages through hormones" - also endocrine

But wait, I should check if any other option fits better. Looking at the list again, B is "Endocrine system" which fits both. However, since these are matching questions, each answer should typically be used once. Let me reconsider...

Hmm, actually rereading the instructions - it says "Draw a line from the question in Column A to the correct answer in Column B." It doesn't explicitly say each answer can only be used once. But typically in these exercises, they are one-to-one matches.

Let me look at what's left after my initial assignments:
Used so far: K, F, I, E, G, D, J, B, L

Remaining options: A (Respiratory), C (Reproductive), H (Lymphatic)

Remaining questions: 10, 11, 12

Q10: "system of organs and glands that controls the body's chemical messages through hormones" - This is definitely endocrine (B)

Q11: "body's protective system by draining and killing toxins to protect from disease" - This sounds like lymphatic system (H) which drains fluids and has immune functions

Q12: "takes in oxygen for the body and expels carbon dioxide" - Respiratory system (A)

So I need to reconsider Q8 and Q10. Let me think...

Q8: "makes hormones and humans" - Wait, let me reread. It says "makes hormones and humans" - that seems odd. Let me assume it means "makes hormones" - Endocrine (B)

Q10: "controls chemical messages through hormones" - Also Endocrine (B)

Since both seem to be endocrine, but we need unique answers, let me see if there's another interpretation...

Actually, looking at the pattern and typical textbook content:
- Q8 might be reproductive (C) if it's saying "makes hormones AND humans" (reproduction)
- Q10 would then be endocrine (B)

That makes sense! The reproductive system makes sex hormones AND creates new humans through reproduction.

Let me redo with this understanding:

Q8: "makes hormones and humans" → C. Reproductive system
Q10: "controls chemical messages through hormones" → B. Endocrine system

Now let me verify all answers:

1. Structure/protection → K. Skeletal ✓
2. Cardiovascular/circulation → F. Circulatory ✓
3. Cleans blood/makes pee → I. Renal/Urinary ✓
4. Largest organ/skin → E. Integumentary ✓
5. Movement → G. Muscular ✓
6. Food to energy/waste removal → D. Digestive & Excretory ✓
7. Neural signals → J. Nervous ✓
8. Makes hormones and humans → C. Reproductive ✓
9. Fights disease → L. Immune ✓
10. Chemical messages/hormones → B. Endocrine ✓
11. Draining/killing toxins → H. Lymphatic ✓
12. Oxygen in/CO2 out → A. Respiratory ✓

All 12 questions matched with 12 unique answers. Perfect!

Final Answer:
1-K, 2-F, 3-I, 4-E, 5-G, 6-D, 7-J, 8-C, 9-L, 10-B, 11-H, 12-A
