Bone Structure: Identifying the Non-Bone Related Term

Circulation does not belong.

Explanation:

The other three terms are all related to the structure and function of bone. Lamellae are the concentric layers of bone tissue that make up the osteon, the basic structural unit of bone. Canaliculi are the tiny channels that run through bone and contain the osteocytes, the cells that maintain bone tissue. Osteoblasts are the cells that build new bone tissue. Circulation is not directly related to the structure of bone, although it is important for the transport of nutrients and oxygen to bone cells and the removal of waste products.
