1. Results:Devitalized bone appeared almost 100% empty lacunae and Haversian Canal broke up in early stage.

2. In the center of each system is an Haversian canal which carries blood vessels.

3. Tissue fluid from the capillaries and connective tissue of the Haversian canal can seep through these spaces and channels, bringing nutrients to the stellate osteocytes residing there.

4. You can see on the left that a central vascular channel ( Haversian canal) is surrounded by concentric lamellae (layers) of bone.

5. Results Under optical microscope, the bone lacunae were in circular permutation around the Haversian canal, and the canaliculi communicated the lacunae and Haversian canal or between the lacunae.
