Valvulae conniventes

The valvulae conniventes, also known as Kerckring foldsplicae circulares or just small bowel folds, are the mucosal folds of the small intestine, starting from the second part of the duodenum, they are large and thick at the jejunum and considerably decrease in size distally in the ileum to disappear entirely in the distal ileal bowel loops. 

They result in a classical appearance on abdominal radiographs, barium studies and CT scans.
