When looking at the picture we see the tree trunk looking things and see that there are a lot of them, they are called Osteon's. Inside the osteons there is the Harversian Canal, which is a blood vessel. There are several layers inside the osteon which are called Lamellae. Inbetween the layers are canaliculi which help the blood travel from the haversian canal to the outer layers. The canaliculi also connect between the lacuunae and inside of the lacuunae we find osteocytes.
