Verified step by step guidance

Understand the role of epithelial tissue: Epithelial tissue serves as a protective barrier, covering the surfaces of the body and lining internal organs and cavities.

Identify the characteristics of epithelial tissue: It is composed of tightly packed cells with minimal extracellular matrix, forming continuous sheets that act as a barrier to protect underlying structures.

Consider the options provided: Storage of minerals, conduction of electrical impulses, contraction to produce movement, and protection of underlying structures.

Evaluate each option: Storage of minerals is a function of bone tissue, conduction of electrical impulses is a function of nervous tissue, and contraction to produce movement is a function of muscle tissue.

Conclude with the correct function: Epithelial tissue primarily functions to protect underlying structures, making this the correct answer.
