[Bioconstruction of the human ileocaecal valve (author's transl)].
The lips of the ileocaecal valve are permanent folds parallel to the long axis of the small intestine, which are formed by invagination of all layers of the terminal ileum into the caecum. In the basal two-thirds they contain processes of all muscular layers of ileum and caecum, which form a system of muscle bundles that is connected with the tunica muscularis mucosae. The luminal part of the lips contains a venous plexus embedded in the loose plexus of the tunica mucosa. Arteriovenous anastomoses facilitate the rapid filling of these venous plexus. The ileocaecal valve in humans acts as a combined angiomuscular-angioplical lock-system that under normal conditions prohibits a caeco-ideal reflux.
