Areolar connective tissue is made of cells and extracellular matrix ("extra-" means "outside", so the extracellular matrix is material that is outside of the cells). Areolar connective tissue is made of cells and extracellular matrix ("extra-" means "outside", so the extracellular matrix is material that is outside of the cells). Connective tissue binds structures together, provides support and protection, fills spaces, produces blood cells, and stores fat.The body uses this stored fat for energy, insulation, and organ protection. The matrix of bone contains collagen fibers and mineral deposits. a sponge, such that 90% of the extracellular matrix is made up Extracellular digestion of the organic components of the bone matrix through liberation of acid hydrolase to the extracellular matrix.
