Epithelial cells that line the small intestine have an adaptation to increase their surface area - what is the name of these structures? And why would the small intestine require a large surface area?

    $\begingroup$ @another'Homosapien' I already found microvillus before coming on here, just to confirm. $\endgroup$ – Sunny Xu Feb 10 '17 at 8:57

They are called microvilli, that forms the brush-border of villi


The small intestine requires a high surface area in order to increase the rate of absorption of digested food.

  • $\begingroup$ The greater surface area also provides for more secretion of the "brush border" enzymes responsible for the finishing touches of digestion. $\endgroup$ – bpedit Feb 9 '17 at 19:05
