Explain of Gastrointestinal Pathology

45.Normal lacteals, gross

This is the normal appearance of terminal ileum. In the upper frame, note the ileocecal valve at the right, and several darker oval Peyer's patches are present on the mucosa. In the lower frame, a Peyer's patch, which is a concentration of submucosal lymphoid tissue, is present. Note the folds are not as prominent here as in the jejunum.
