What are the smallest projections of the small intestine wall?​

Quizplus · Accepted Answer

Microvilli are the smallest projections of the small intestine wall. They increase the surface area of the intestinal lining, allowing for more efficient absorption of nutrients. Cilia are not found in the small intestine, villi are larger than microvilli and consists of many cells, brush border cells is a general term for the cells at the border of the intestinal lining, and duodena is incorrect as it refers to a part of the small intestine rather than a projection on the wall.
