Verified step by step guidance

Understand the basic characteristics of epithelial tissue. Epithelial tissue is a type of tissue that lines the surfaces and cavities of organs and structures throughout the body.

Identify the concept of polarity in epithelial tissue. Polarity refers to the presence of structural and functional differences between the apical (top) and basal (bottom) surfaces of the epithelial cells.

Recognize the avascular nature of epithelial tissue. Avascularity means that epithelial tissue does not contain blood vessels and relies on diffusion from underlying tissues for nutrients and waste removal.

Consider the presence of extracellular matrix. Epithelial tissue typically has minimal extracellular matrix compared to other tissue types like connective tissue.

Review the characteristics listed in the problem and match them with the known features of epithelial tissue: polarity and avascularity are correct, while abundant blood supply and presence of extracellular matrix are not typical characteristics of epithelial tissue.
