Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. Cartilage contains chondrocytes which produce the cartilage matrix. C. The bone would be more brittle. Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function. Short, irregular, and flat bones have large marrow cavities in order to keep the weight of the bones light. Osseous tissue comes in two forms, both of which are present in every bone in the body: compact bone and spongy bone. -spongy bone: composed of trabeculae and has much open space; space between the trabeculae is filled with marrow.

Bone Tissue • Bone is alive and continuously changing. Bone tissue (osseous tissue) is a hard tissue, ... Cancellous bone is highly vascular and often contains red bone marrow where hematopoiesis, the production of blood cells, occurs. This gives strength and flexibility to the tissue.
