Verified step by step guidance

Understand the primary function of epithelial tissue: Epithelial tissue is specialized for covering body surfaces, lining internal cavities, and forming protective barriers. It is not primarily involved in contraction and movement, which is a function of muscle tissue.

Examine the structural characteristics of epithelial tissue: Epithelial cells are tightly packed with minimal extracellular space between them, forming continuous sheets. This ensures effective protection and selective permeability.

Analyze the vascularization of epithelial tissue: Epithelial tissue is avascular, meaning it does not contain blood vessels. Nutrients and waste exchange occur through diffusion from underlying connective tissues.

Identify the correct description of epithelial tissue: The statement 'Epithelial tissue covers body surfaces and lines internal cavities' accurately describes its primary function and structural role in the body.

Conclude that the other statements are incorrect based on the functional and structural properties of epithelial tissue, reinforcing the correct answer provided in the problem.
