Does the ileum have plicae circulares?
The distinguishing feature of the ileum is the presence of large groups of lymphatic nodules in the lamina propria called Peyer’s patches . The plicae circulares (valves of Kerckring) in this slide are not as prominent as those found in the duodenum and jejunum. Goblet cells are most numerous in the terminal ileum.
What is the lacy apron of the peritoneum?

What are the folds in the colon called?
The inner wall of the small intestine is covered by numerous folds of mucous membrane called plicae circulares. The surface of these folds contains tiny projections called villi and microvilli, which further increase the total area for absorption.
What is Kerckring?
What does Opacified bowel mean?
The normal small bowel wall thickness is 3 mm or less. This means that a bowel loop opacified with contrast has essentially no definable wall. The presence of wall thickening, although not a specific marker for a disease entity, is diagnostic of bowel pathology.
