Question

Quizplus · Accepted Answer

The surface projections on the epithelial cells lining the small intestine that increase the rate of nutrient absorption are called microvilli. Villi are finger-like projections on the surface of the small intestine that increase its surface area, but do not directly increase nutrient absorption. Cilia are hair-like projections that aid in movement, but are not present on the surface of the small intestine. Parietal cells are cells in the lining of the stomach that secrete hydrochloric acid for digestion.
