Detail of an intestinal villus observed with the objective of 40x. We can see the intestinal lumen in contact with the unistratified epithelium, formed by prismatic cells (provided with glycocalyx) and secretory cells. Under the epithelium is placed the lamina propria, formed by conjunctive tissue and blood vessels, which can not be observed in this section. The epithelium can be viewed at higher magnification in other microphotography (zone framed in red)
