What type of tissue serves as protective tissue such as skin?

Epithelial tissue serves as protective tissue, including the skin. This type of tissue acts as a barrier that protects the underlying structures of the body from physical damage, pathogens, and dehydration. The skin, the largest organ in the body, is composed mainly of epithelial cells, specifically stratified squamous epithelium, which is adapted for protection due to its multiple layers. Epithelial tissue also plays critical roles in absorption, secretion, and sensation, but its fundamental characteristic is its protective function, which is essential for maintaining overall health and preventing injury from environmental factors.

Muscle tissue, on the other hand, is primarily responsible for movement; connective tissue supports, binds, and protects other tissues and organs; and nerve tissue is involved in the transmission of signals throughout the body. Each of these tissues has distinct roles that do not include serving as a primary source of protection like epithelial tissue does.
