block10-1_23.jpg - Fig 10. 93W4523 Digestive system, Composite (sec.) H&E.There are three tissues in this slide: upper, colon; middle,small intestine; lower, stomach.The second tissue of this slide is a longitudinal section of thesmall intestine. The layers of the wall, in order from the lumen,are the mucosa, the submucosa, the muscularis externa, andthe serosa (extremely thin layer in this slide). The mucosareveals several longitudinally sectioned villi and cross-sectioned crypts of Lieberkuhn. The intestinal villi are lined bya simple columnar epithelium which is continuous with thecrypts of Lieberkuhn. The crypts of Lieberkuhn extend as faras the muscularis mucosa.
