The structure through which the vessels pass in the bone, is called Havers duct, and these in turn are located inside the bone canalicules, if a response is to be chosen, serious bone canalicules.
Central channels are a series of narrow tubes within the bones through which blood vessels pass. They are formed by concentric coverslips of collagen fibers. They are found in the most compact region of the bone shaft (long bone medium). They can be seen at the center of osteons in histological sections of the bones. It has the function of nourishing the bones and enabling blood vessels to pass through the bone matrix.
