Question 34

cartilage types

Answer 34

hyaline, elastic, fibrocartilage

Question 35

hyaline cartilage

Answer 35

helps your bones move smoothly past each other in your joints. It's flexible but strong enough to help your joints hold their shape. Slippery

Question 36

Elastic cartilage

Answer 36

a type of cartilage that provides both strength and elasticity to certain parts of the body, such as the ears. Allows stuff to maintain original shape when altered
