Answer
villi
The final answer is villi
Answer for screen readers
The final answer is villi
More Information
Villi are small, finger-like projections that extend into the intestinal cavity, increasing the surface area significantly for food absorption. These structures are further enhanced by microvilli, which maximize absorption efficiency.
Tips
Do not confuse villi with microvilli. Microvilli are smaller projections on the villi, further increasing the surface area.
