Let’s solve this step by step.

Part I: Match the human body system to its function
We need to match each numbered system (1–11) with the correct lettered description (A–K).
Let’s go one by one:
1.
Skeletal system → This is the framework of bones that supports the body.
→ Matches
A
2.
Muscular system → Works with skeletal system to allow movement.
→ Matches
E
3.
Respiratory system → Brings in oxygen, removes carbon dioxide.
→ Matches
B
4.
Circulatory system → Circulates blood throughout the body.
→ Matches
K
5.
Excretory system → Removes waste products from the body.
→ Matches
H
6.
Nervous system → Controls all bodily functions (like thinking, sensing, reacting).
→ Matches
D
7.
Immune system → Protects against infections and diseases.
→ Matches
F
8.
Integumentary system → Includes skin, which protects from outside world.
→ Matches
G
9.
Endocrine system → Produces hormones to regulate body conditions.
→ Matches
I
10.
Reproductive system → Allows organism to reproduce more of its own kind.
→ Matches
C
11.
Digestive system → Transforms food into forms the body can use.
→ Matches
J
✔ All matches are now done.
