Which intestinal features increase absorptive surface area and what is the role of villi and microvilli?

• A. Villi and microvilli increase surface area; enterocytes absorb nutrients via transporters; lacteals absorb lipids; capillaries absorb monosaccharides and amino acids.
• B. Intestinal crypts increase surface area; goblet cells absorb nutrients.
• C. Microvilli reduce surface area; enterocytes secrete hormones.
• D. Villi do not affect absorption; microvilli uptake water.
