Small Intestine, villi

Notes

The villi of the small intestine are lined by simple columnar epithelium composed primarily of absorptive cells (enterocytes), with scattered goblet cells.  

Mucus in goblet cells stains poorly with H&E.  In this micrograph, goblet cells appear as pale spots (blue arrowheads).

(Enteroendocrine cells also occur in the intestinal epithelium, but none are apparent on this micrograph.)

Lamina propria forms the core of each villus and contains a single lacteal.
