Verified step by step guidance

Understand the characteristics of epithelial tissue: Epithelial tissue is specialized for covering surfaces, lining cavities, and forming glands. It has distinct features such as avascularity, a basement membrane, and tightly packed cells.

Clarify the term 'avascularity': Epithelial tissue lacks blood vessels, meaning it relies on diffusion from underlying connective tissues for nutrients and waste exchange.

Examine the basement membrane: Epithelial cells rest on a thin layer called the basement membrane, which provides structural support and separates the epithelium from underlying tissues.

Analyze the extracellular matrix: Epithelial tissue has minimal extracellular matrix because the cells are tightly packed together to form protective barriers.

Evaluate the statement 'abundant blood supply within the tissue': This contradicts the avascular nature of epithelial tissue, making it the correct answer to the question.
