What is a characteristic of epithelial cells?

They have a low capacity for renewal

They are arranged in continuous sheets (correct)

They are found only in internal organs

They have a large amount of extracellular material

What is the function of the apical surface of epithelial cells?

It is attached to a basement membrane

It is responsible for absorption

It is exposed to the exterior of the body (correct)

It is involved in secretion

Why do epithelial cells have a high capacity for renewal?

Because they are avascular

Because they are found in internal organs

Because they are subjected to wear and tear (correct)
