Which list shows the correct order of living units, from smallest to largest ? a. bone, osteocyte, periosteumb. periosteum, bone, osteocytec. bone, periosteum, osteocyted. osteocyte, periosteum, bone

C. bone, periosteum, osteocyte

Explanation:

Bone is a structure formed by bone tissue, a type of very rigid connective tissue characterized by the presence of calcium, collagen fibers and proteoglycans. They are whitish and hard organs that join together by joints to form the body's skeleton. It has the smallest size when compared to the periosteum and osteocyte. The bones are covered by layers of tissue and cells, constituting the periosteum and endosteum.

The periosteum, which is a layer of connective tissue that covers the bones, has the function of receiving nutrients and passing to the other layers by diffusion. How it covers the bone needs to be bigger than it.

The osteocyte is a bone cell part of the bone tissue, that is, it is intrinsic to the bones, is housed precisely in its matrix, the most important part of a bone. It is housed more precisely in a small cavity through which it spreads extensions that come in contact with other osteocytes forming a complex system. It is the largest structure in relation to those mentioned above.
