Jejunum or ileum
The jejunum and ileum (shown here) can be differentiated from the duodenum, primarily by the lack of glands in the submucosa. Villi of the small intestine possess a lacteal that transports absorbed lipids to lymphatic vessels in the submucosa. A plica circularis, a circular fold of submucosa and its overlying mucosa, is centrally located in the image. 40x

Muscularis externa >
In this longitudinal section, the muscle fibers in the inner circular layer of the muscularis externa are cut in cross section (yellow arrows); fibers in outer longitudinal layer of the muscularis externa are cut lengthwise (red arrows). Auerbach’s plexus is located between these layers of smooth muscle.
