Dünndarmschleimhaut
The Dünndarmschleimhaut, or small intestinal mucosa, is the inner lining of the small intestine. It is a highly specialized tissue crucial for the digestion and absorption of nutrients. This layer is characterized by its folded structure, which significantly increases the surface area available for absorption. These folds are further amplified by villi, finger-like projections that protrude from the surface, and even smaller microvilli on the surface of individual absorptive cells, known as enterocytes.
The primary function of the Dünndarmschleimhaut is to absorb digested food particles, water, and electrolytes from
This mucosal lining also plays a role in the immune system. It contains specialized immune cells and
