Quizplus · Accepted Answer

Microvilli are finger-like projections on the surface of epithelial cells that line the intestine, designed to increase the surface area available for nutrient absorption. Rugae are folds in the stomach lining that help the stomach expand during digestion. Cilia are hair-like structures that help move substances along the surface of cells. Villi are also finger-like projections on the surface of intestinal cells, but are larger and contain blood vessels and lymphatic vessels for nutrient transport. However, the question specifically asks for the "surface projections" that increase nutrient absorption, which is best represented by microvilli.
