  1. To move mucus toward the anus
  2. To secrete hormones like gastrin
  3. To anchor the epithelial cells to the lamina propria
  4. To increase surface area and host digestive enzymes
Show answer and explanation

Correct answer: To increase surface area and host digestive enzymes

The brush border consists of thousands of microvilli that vastly increase the cell's surface area. It also contains enzymes like disaccharidases and peptidases that perform the final stages of digestion.
