Nutrients and oxygen reach osteocytes through tiny canals called canaliculi, which connect the cells to the blood vessels in the Haversian canal. IV. Conclusion

Strength is provided by the inorganic mineral salts (calcium and phosphorus), while the organic fibers (collagen) provide flexibility. The tubular structure of osteons ensures maximum strength with minimum weight.
