Quizplus · Accepted Answer

The transverse folds of the intestinal lining are called circular folds, which increase the surface area available for absorption of nutrients. Rugae are folds in the stomach lining that allow for expansion. Mucous glands secrete mucus to protect the lining from damage. Villi and microvilli are finger-like projections on the surface of the small intestine that further increase surface area for absorption.
