the Skeleton


Slide 1 - Tekstslide

Bones and cartilage
The skeleton consists out of 2 types of tissue: 
Bone and cartilage 

But..
What are bones made of?

Slide 2 - Tekstslide

Structure of bones
Bones exist out of calcium phosphate and collagen

Calcium phosphate makes the bone strong and rigid.
Collagen makes the bone flexible

Slide 3 - Tekstslide

Changes of bone tissue
The skeleton of a baby consists mostly of cartilage tissue.
During growth, most of the cartilage changes to bone.

When you get older:
--> Amount of collagen decreases
--> amount of calcium phosphate increases.





Slide 4 - Tekstslide

baby is flexible because they have a lot of collagen in their bones
