5.Blood Cell Formation: Blood cells are produces in the soft marrow tissue that fills the internal cavities of some bones.What is the axial skeleton?
Bone StructureDescribe the layers of bone:∙Cartilage∙Spongy Bone∙Compact Bone∙Bone Marrow∙Periosteum∙Osteoclast∙Osteoblast∙Cartilage: A dense and fibrous substance that is strong, but flexable. Found in places like the nose and ear, where bones meet, and near the growth plates at either end of long bones. Cartilage cells recieve nutrients throughdiffusion from the neighboring blood vessels and tissues.∙Spongy Bone: A strong netwrok of thin fibers that adds strength to the bone
