periosteum
Nutrients in compact bone are delivered to osteocytes via tiny channels called canaliculi that connect the osteocytes to nearby blood vessels in the central Haversian canals. This interconnection allows for the exchange of nutrients and waste products, supporting the metabolic needs of the bone cells.

Osteonic canals contain blood vessels that connect to the long axis of the bone. The blood vessels that are connected perforate the canals of the bone and provide vessels to the surface of the bone which makes the bone hard.
Haversian canals in compact bone contain blood vessels, nerves, and lymphatic vessels that supply nutrients and remove waste products to and from osteocytes within the bone. They provide a network for communication and transportation throughout the bone tissue to maintain its health and function.
The central canal in the center of an osteon is called the Haversian canal. It contains blood vessels and nerve fibers that supply the osteocytes within the osteon.
osteoblast
Blood vessels that nourish the osteocytes travel through the Haversian or Volkmann's canals within the bone tissue. These canals provide a pathway for blood supply to reach the osteocytes, ensuring they receive necessary nutrients and oxygen for their metabolic activities.
each osteocyte is interconnected with other osteocrytes via canaliculi. Canaliculi are tube-like tunnels that transport nutrients to the osteocytes, from the blood vessels
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).
The horizontal canal in an osteon is a small channel that connects adjacent osteocytes within the bone. It allows for the exchange of nutrients and waste products between the osteocytes and the blood vessels that supply the bone. This network of canals helps to maintain the health and function of bone tissue.
The bone cells in the Haversian system are found in small spaces called lacunae. These lacunae house osteocytes, which are the mature bone cells that maintain bone tissue. The Haversian system, or osteon, is the structural unit of compact bone, consisting of concentric lamellae surrounding a central canal that contains blood vessels and nerves.
