Question

Quizplus · Accepted Answer

The basement membrane provides support and anchorage for the epithelial tissue, regulates exchange of materials, and separates different tissue types, but it does not produce a waterproof barrier of cells. The waterproofing function is typically attributed to specific cell junctions within the epithelial cells themselves, such as tight junctions.
