Answer:
Microvilli function to increase the functional absorptive capacity of the small intestine cells
Explanation:
Microvilli cover the apical surface of the intestinal absorptive cells, (i.e., enterocytes), thereby increasing the surface absorption area of the small intestine from 20 to 1000-fold. Microvilli are numerous projections that have only one dimension beyond 100 nanometers (nm) and form a fingerlike brush border. In a similar manner to the experiment that involves two papers towels contacting two cups of colored water, this formation can significantly increase the velocity of absorption because the colored water molecules have higher surface to move faster from the cup that is in contact with the paper in a zigzag way.
