WebJan 11, 2024 · Examine the villi at a higher magnification and note that the lining epithelium consists of simple columnar cells (aka enterocytes) with a brush border and interspersed goblet cells, particularly well-demonstrated in slide 168. The epithelium lining the villi continues into the intestinal glands. Intestinal villi dysfunction leads to malabsorption, so symptoms are typically consistent with nutrition deficiencies and digestive issues. These may include:2 1. Bouts of diarrhea 2.
