1. Describe Ossification during Fetal Development. Ossification is the formation of bone and in a fetus is made up of cartilaginous tissue. This tissue is less dense than that of bony tissue. Over time‚ as calcium salts are being deposited into the cartilaginous tissue by immature bone cells‚ the formation of bone occurs. 2. What are the roles of Osteoclasts in bone formation? Osteoclasts reabsorb bony tissue from the innermost part of the bones‚ allowing for a larger cavity‚ in order to avoid

These parts are major organs‚ the brain is protected by the skull‚ the lungs and heart are protected by the ribs and the vertical column protects the spinal cord.
