Villi and microvilli are structures that increase the surface area for absorption. The jejunum is part of the small intestine where most nutrient absorption occurs. The duodenum (initial part of small intestine) has some villi but less than jejunum. Stomach has gastric pits, colon (large intestine) has different structures for water absorption, ileum (last part of small intestine) has fewer villi compared to jejunum.
