The human skeleton has 206 bones that perform several essential functions: providing structure and shape to the body like a framework; protecting vital organs like the brain and lungs; enabling movement through joints and muscles pulling on bones; producing blood cells in the marrow; and storing important minerals like calcium. The skeleton is critical to survival, as without it our organs would be easily injured and our bodies would have no structure or ability to move.

4. Overview: Human Skeleton
 There are 206 bones in the human skeleton.
 Functions of the skeleton:
 Gives structure and shape to the body
 like the framework of a house.
 Provides protection for the organs
 such as the heart and brain.
 Blood cells are produced in the bones
 in the marrow new cells are produced and damaged ones are repaired.
 Movement
 muscles pull on the bones to move body parts.
 Mineral Storage
 important minerals such as calcium are stored in the bones.

5. Protection
 The skeleton protects vital organs inside the body.
 Such as:
 The skull protects the brain
 The rib cage protects your heart and lungs
 The pelvis protects digestive and reproductive organs
Without this hard shell, our organs would be easily injured.

6. Structure and Shape
 The skeleton provides the body with structure and shape;
much like the framework of a house.
 The other parts of our body like our skin and muscles form around the
bones; much like the walls around the frame of a house.
Without these bones to offer structure and shape, our bodies would be
blobs like jelly fish.

7. Blood Cell Production
 The marrow inside of bone is where most of the
blood cells are made. Red blood cells are produced
here; they help carry oxygen throughout the body.
Platelets are also found here; they help with wound
healing.

8. Mineral Storage
 Bones need calcium to keep their hardness and strength.
 Other minerals stored in bone include phosphorus and
vitamin D.

9. Movement
 Muscles pull on the bones in order to move them
 Joints are formed where two
bones meet, allowing for
movement.
 The bones, along with the
muscles and tendons work
together to move the body
and perform every day
movements.
