Verified step by step guidance

Understand the structure and function of matrix tissues: Matrix tissues are composed of cells embedded in an extracellular matrix, which provides structural and functional support. Examples include cartilage, bone, and connective tissues.

Review the anatomy of compact bone: Compact bone contains central canals (also known as Haversian canals) that house blood vessels and nerves, forming the osteon system.

Examine the structure of spongy bone: Spongy bone, also called cancellous bone, lacks central canals. Instead, it has trabeculae, which are porous and allow for the diffusion of nutrients and waste without the need for central canals.

Analyze cartilage: Cartilage is a flexible connective tissue that lacks blood vessels and central canals. Nutrients diffuse through the matrix to reach the chondrocytes.

Consider dense regular connective tissue: Dense regular connective tissue is composed of tightly packed collagen fibers and fibroblasts, but it does not have central canals. It is designed for tensile strength rather than nutrient transport.
