The Haversian canals carry blood vessels and nerves to and from the bone.
Volkmann's canals are nerves that run across the surface of the bone.
The long hollow passageway, the Haversian canal, contains small blood vessels responsible for the blood supply to osteocytes (individual bone cells).Osteons are several millimetres long and about 0.2 millimeter (0.008 inch) in diameter; they tend to run parallel to the long axis of a bone.
The Haversian canals
The perforating (Volkmann) canals, that run horizontally in compact bone and connect to the central canal.
The Haversian canals carry blood vessels and nerves to and from the bone.
In compact (dense) bone, the nerves and blood vessels run through conduits known as the Haversian Canals. These are connected to the bone cells by canaliculi channels.

They are part of the microscopic structure of compact bone. Compact bone is solid, dense, and smooth.The structural unit of compact bone is the Haversian system or Osteon. These are elongated cylinders cemented together to form the long axis of a bone.Components of Haversian system consists of 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.Each system has communicating canals within compact bone with other systems.

Bone marrow
in the marrow of bones im pretty sure (blood vesels run through small holes in the bone) i heard this in science class and im probably right
Under the microscope dense, compact bone shows a definite and a characteristic pattern of arrangement. The ground substance of bone is arranged in concentrated layers (lamellae) round the small canals which run parallel to the long axis (shaft) of the bone. These canals, called Haversian canals, are interconnected with one another via Volkmann's canals and contain a blood vessel, a nerve and a lymph vessel. Each Haversian canal is surrounded by concentric layers of bone matrix (called lamallae) and concentric rings of bone forming cells (osteoblasts). Bone cells remain alive and once they have completely surrounded by the hard bone matrix, they are called osteocytes. The osteocytes are embedded in fluid-filled cavities within the concentric lamellae. These cavities are known as lacunae and occur at regular intervals in these concentric layers of bone tissue. The lacunae are connected to one another and to the Haversian canals by a system of interconnecting canals known as canaliculi. Each Haversian canal, its concentric lamellae, lacunae with osteocytes and canaliculi forms a long cylinder and is called a Haversian system. Separate Haversian systems are joined to each other by means of interstitial lamellae.
The irrigation system is the process of supplying water to a field etc... through a system of tunnels or canals that run through the field.
