The role of collagen in connective tissues is to provide structural support and strength. Collagen fibers form a network that gives tissues their elasticity and integrity. This protein is prevalent in various connective tissues, including cartilage, tendons, and skin, making it essential for maintaining tissue resilience and stability. Additionally, collagen plays a vital role in wound healing and tissue regeneration, enabling proper recovery from injuries. Its significance extends to various biological processes and is crucial for overall connective tissue health.
