What describes the function of fibroblasts in the human body?

Fibroblasts play a crucial role in the human body's connective tissue. Their primary function is to produce collagen, which is a key structural protein that provides strength and support to various tissues, including skin, tendons, and ligaments. Collagen is vital for maintaining the integrity of these structures, giving them the ability to withstand stretching and strain.

In addition to collagen, fibroblasts also produce other components of the extracellular matrix, such as elastin and glycosaminoglycans, which contribute to the overall structural framework and hydration of tissues. While other cells in the body handle different functions—such as producing proteins for skin protection, assisting in immune responses, or producing pigments for UV protection—fibroblasts are specifically dedicated to the synthesis of collagen, making this choice the most accurate representation of their primary role.
