VALVULAE CONNIVENTES Meaning and
Definition
-
Valvulae conniventes, also known as plicae circulares, are corrugated folds found in the inner lining of the small intestine that help increase the surface area for nutrient absorption. These structures can be described as finger-like projections or ridges that extend into the lumen, or hollow space, of the intestine. They are composed of mucosa and submucosa layers and are covered by both simple columnar epithelial cells and enterocytes.
The primary function of the valvulae conniventes is to enhance nutrient absorption by increasing the surface area available for contact with digestive enzymes and facilitating the movement of nutrients into the bloodstream. By creating an uneven and convoluted surface, these folds maximize the absorptive capacity of the small intestine.
Valvulae conniventes are particularly prominent in the first two sections of the small intestine, the duodenum, and the jejunum. They gradually become less pronounced in the ileum, the last part of the small intestine. The presence of these folds distinguishes the small intestine from other parts of the gastrointestinal tract, such as the large intestine, which lacks such structures.
Overall, valvulae conniventes play a crucial role in the efficient digestion and absorption of nutrients in the small intestine by increasing surface area. Their unique anatomical arrangement allows for optimal interaction between digested food particles and the absorptive cells that line the intestinal wall.
