Verified step by step guidance

Understand the structure and function of the epidermis: The epidermis is the outermost layer of the skin, designed to protect the body from environmental damage, pathogens, and water loss. It requires a durable and protective tissue type.

Review the characteristics of stratified squamous epithelium: This tissue type consists of multiple layers of cells, with the outermost layers being flat (squamous) and designed to withstand abrasion and provide a barrier function.

Compare the other tissue types listed: Simple cuboidal epithelium is a single layer of cube-shaped cells, typically found in glands and ducts. Pseudostratified columnar epithelium appears layered but is not, and is commonly found in the respiratory tract. Transitional epithelium is specialized for stretching and is found in the urinary bladder.

Identify why stratified squamous epithelium is the correct answer: The epidermis requires a tissue type that can endure constant wear and tear, making stratified squamous epithelium the most suitable choice due to its multiple layers and protective properties.

Conclude that the epidermis is composed of stratified squamous epithelium, which aligns with its protective role in the body.
