What is the role of collagen fibers in connective tissue?

Collagen fibers play a crucial role in providing structural support and rigidity to connective tissues. They are the most abundant proteins in the extracellular matrix and are responsible for giving strength and stability to various tissues in the body, such as tendons, ligaments, and cartilage. The tensile strength of collagen helps to resist stretching forces and contributes to the overall integrity of connective tissues, making it essential for maintaining the shape and function of organs and structures within the body.

In contrast, other options like providing elasticity is primarily the function of elastin fibers rather than collagen. Storing energy is associated with adipose tissue rather than the roles of collagen. Facilitating movement involves muscular action and the coordination of various tissue types, where collagen provides passive support rather than active movement. Overall, the unique properties of collagen make it indispensable for the proper function of connective tissues.
