Explanation:
-
Skeletal System Basics: The skeletal system is composed of
bones, which provide structural support, protect internal organs, and facilitate movement through interaction with muscles.
-
Bone Count: Humans typically have
206 bones as adults, but babies have more due to the fusion of some bones during growth.
-
Protection by Bones:
- The
rib cage protects vital organs like the
heart and
lungs.
- The
skull protects the
brain.
This worksheet helps reinforce these fundamental concepts in a simple and engaging way.
Final Answer:
\boxed{
\text{1. bones, 2. 206, 3. adult, baby, 4. shape, 5. muscles; Rib cage: Heart, Lungs; Skull: Brain}
}
