Verified step by step guidance

Understand the primary functions of epithelial tissue. Epithelial tissue serves several key roles in the body, including secretion, absorption, and protection.

Secretion involves the production and release of substances such as enzymes, hormones, and mucus. Epithelial cells in glands are specialized for this function.

Absorption is the process by which epithelial cells take in substances from the external environment or from internal cavities, such as nutrients in the intestines.

Protection is a crucial function of epithelial tissue, as it forms a barrier against mechanical injury, pathogens, and fluid loss.

Recognize that contraction is not a function of epithelial tissue. Contraction is primarily a function of muscle tissue, which is responsible for movement and force generation in the body.
