Verified step by step guidance

Understand the role of collagen in the human body: Collagen is a structural protein that provides strength and support to various tissues, including skin, bones, and connective tissues.

Identify the cells responsible for collagen synthesis: Collagen is synthesized by fibroblasts in connective tissues, not by osteoclasts, which are involved in bone resorption.

Differentiate between tissue types: Collagen is not a type of epithelial tissue; it is a protein found in connective tissues.

Clarify the function of collagen fibers: Collagen fibers provide tensile strength, not elasticity. Elasticity in the skin is primarily due to elastin fibers.

Recognize the abundance of collagen: Collagen is indeed the most abundant protein in the human body, making up a significant portion of the total protein content.
