Villi are finger-like projections that increase the surface area of the small intestine for absorption.

Answer: A
 The spiral valve is a structure found in the intestines of some fish that increases surface area for absorption by creating a spiral-shaped path for food.

Answer: B
 The typhlosole is a spiral-folded structure found in the intestine of some invertebrates, such as earthworms, that increases surface area for absorption.

Answer: E
 Lacteals are small lymphatic vessels in villi that play a role in fat absorption.

Answer: C
 The large intestine does not function to increase surface area for absorption. Instead, it is mainly responsible for absorbing water and electrolytes and forming feces.
