Answer:

Bone cells remain alive and recieve nutrition by blood. In order to deliver nutrients to and remove waste from the bone, the hard and compact surface of the bone is pierced by "canals" through which blood vessels can travel.

Explanation:

In the bone, blood is supplied by three separate systems: a nutrient artery, periosteal vessels, and epiphyseal vessels. These blood vessels run in the central canal.

Nutrients are carried by these blood vessels to the bone and the waste is also removed by the blood.
