Compact pact bone also stores calcium spongy bone - AnswerDue to the sponge-like or porous nature of spongy or cancellous bone, spongy bone has a greater surface area compared to compact bone. This allows bone marrow to develop in the region of spongy bone osteoclasts - Answerbone cell that absorbs bone tissue during growth and healing osteoblasts - Answera cell that secretes the matrix for bone formation bone function - Answershape, support, and protect body structure, blood cell formation, salt storage How are bones classified? - Answerlong bones- femur, humerus short bones- carpal flat bones- frontal bone of skull irregular bones- vertebra sesamoid- patella
