Tissues, Glands, and Membranes Connective Tissue Connective tissue holds cells and tissues together. Connective tissue has an extracellular matrix consisting of protein fibers, ground substance, and fluid. Collagen fibers are flexible but resist stretching, reticular fibers form a fiber network, and elastic fibers recoil. Blast cells form the matrix, cyte cells maintain it, and clast cells break it down. Functions of Connective Tissue Connective tissues enclose and separate; connect tissues to one another; and support, store, cushion, insulate, transport, and protect. Classification Connective tissue that has protein fibers as the primary feature of the extracellular matrix are dense connective tissue (tendons, ligaments, and dermis of skin), loose connective tissue ("loose packing" material of the body), and adipose tissue. Connective tissue that has protein fibers and ground substance as important features of the extracellular matrix are cartilage and bone. Connective tissue that has a fluid matrix is blood.
