osteoblast
Blood vessels running through the Haversian canals...
each osteocyte is interconnected with other osteocrytes via canaliculi. Canaliculi are tube-like tunnels that transport nutrients to the osteocytes, from the blood vessels
The circulatory system brings blood containing nutrients and oxygen to the periosteum, which covers the bone. The periosteum is a thin membrane that contains nerves and blood vessels. Its main function is to provide nourishment to the bone. From the periosteum, nutrients and oxybgen go through the perforating canals to the central canal, and then to the canaliculi. The osteocyte nearest the central canal passes nutrients to the next osteocyte with arm-like extensions that extend into the canaliculi to the next osteocyte. At the terminal end of each extension, gap junctions connect the cytoplasm of each osteocyte so that nutrients/wastes can be passed between cells to/from the central canal.

Haversian canal
The three are all cells that can be found in the bone. Osteoclast -Break down the bone. Osteocyte- Carry nutrients and waste products to and from the blood vessels in the bone. Osteoblast - Create new bone and repair damage.
Components of Haversian system: osteocytes (spider-shaped bone cells that lie in "lacunae") that have laid down a matrix of collagen and calcium salts in concentric lamellae (layers) around a central Haversian canal containing blood vessels and nerves.The Haversian canal contains small blood vessels responsible for the blood supply to osteocytes (individual bone cells).
Canaliculi are tiny channels in bone tissue that allow for the exchange of nutrients and waste between osteocytes (bone cells) and blood vessels. They help maintain the health and function of bone by facilitating communication and transport within the bone tissue.
Osteocytes are mature bone cells surrounded by matrix which solid bone cell ground substances attach to. Bone cells are in the proximity of blood vessels, just like any other cell in the body. Bones only have cells in their growth areas and in the bone marrow, where blood cells are also produced.
Epidermal cells are supplied with nutrients from blood vessels in the
Spider-shaped mature bone cells, called OSTEOCYTES, live in small spaces in the lamellae called LACUNAE. Tiny canals, called CANALICULI, connect the lacunae to each other and to the Haversian canal. The canaliculi contain slender, tentacle-like cellular processes of the osteocytes. The canaliculi provide routes through which nutrients and oxygen from the blood can reach the osteocytes and waste products (ammonia, carbon dioxide) can be removed and eventually carried away by blood vessels in theHaversian canals.
