Which term describes epithelium that covers the body surfaces, lines body cavities, lines ducts of organs and glands, lines vasculature, lines the organs, and forms the secretory portions of glands?

Explanation:
Epithelial tissue covers body surfaces and lines cavities, ducts, vessels, and organs, and it also forms the secretory portions of glands. This tissue is organized into continuous sheets of tightly connected cells with a basement membrane, shows apical and basolateral polarity, and is typically avascular. It can differentiate to form secretory units in glands, which is why it both lines and forms glands. The other options describe different terms: a cell is a single unit, not the tissue type that lines and covers; muscle tissue is for contraction; nervous tissue transmits signals. So the term that fits all the described roles is epithelial tissue.
