Verified step by step guidance

Step 1: Understand the role of epithelial tissue in the body. Epithelial tissue primarily serves as a protective barrier, covering surfaces such as the skin and lining internal organs, cavities, and blood vessels.

Step 2: Compare the functions listed in the question with the known functions of epithelial tissue. Epithelial tissue does not store minerals, produce blood cells, or initiate voluntary movement. These functions are associated with other tissues like bone, bone marrow, and muscle tissue respectively.

Step 3: Focus on the function 'Protection of underlying structures.' Epithelial tissue is specialized to protect underlying tissues from physical damage, pathogens, and dehydration, which aligns with this option.

Step 4: Recall examples of epithelial tissue performing protective functions, such as the skin (epidermis) protecting against environmental damage and the lining of the respiratory tract preventing pathogen entry.

Step 5: Confirm that 'Protection of underlying structures' is the correct answer based on the primary function of epithelial tissue as described in anatomy and physiology.
