This connective tissue contains collagen fibers for flexibility and strength, and numerous elastic fibers that enable it to be stretched.

In vertebrates, the most common type of connective tissue is loose connective tissue. It holds organs in place and attaches epithelial tissue to other underlying tissues.oose Connective Tissue. 1  Collagenous Fibers. 2  Collagenous fibers are made of collagen and consist of bundles of fibrils that are coils of collagen molecules. 3  Elastic Fibers. 4  Elastic fibers are made of the protein elastin and are stretchable. 5  Reticular Fibers. 6  Reticular fibers join connective tissues to other tissues.
