Ileum, Peyer's patch

Notes

The mucosa of the ileum is typical of the small intestine, with the addition of conspicuous patches of lymphoid tissued called Peyer's patches, which may protrude into the lumen and also extend into the submucosa (as illustrated here in a non-human example).  

Muscularis externa of the ileum has the standard inner circular and outer longitudinal layers of smooth muscle.
