Functions of bones (write in blank space) Storage—of minerals,

especially calcium and phosphate

Protection—red marrow found in developing bones and adults in flat bones (pelvis, ribs, skull, backbone, long bones.

Types of bones Long-greater length than width

Short-cube shaped Flat bones-thin, broad Irregular-complex shapes
