What is the function of cells in the digestive system?
Absorptive cells, or enterocytes, are the predominant epithelial cell type lining the lumen of the small intestine and colon. These cells are specialized for absorption of nutrients across the apical plasma membrane and export of these same nutrients across the basal plasma membrane.Click to see full answer.

Absorptive cells, or enterocytes, are the predominant epithelial cell type lining the lumen of the small intestine and colon. These cells are specialized for absorption of nutrients across the apical plasma membrane and export of these same nutrients across the basal plasma membrane.Click to see full answer. Also question is, what is the function of the intestinal cell?The intestinal epithelium is a single layer of cells organized into crypts and villi, known as the most rapidly self-renewing tissue in adult mammals. The cells that line the intestinal lumen perform the primary functions of digestion, water and nutrient absorption, and forms a barrier against luminal pathogens.Likewise, what cells and tissues are in the digestive system? The mucosa consists of epithelium, an underlying loose connective tissue layer called lamina propria, and a thin layer of smooth muscle called the muscularis mucosa. In certain regions, the mucosa develops folds that increase the surface area. Certain cells in the mucosa secrete mucus, digestive enzymes, and hormones. Subsequently, one may also ask, what are the 4 main functions of the digestive system? To achieve the goal of providing energy and nutrients to the body, six major functions take place in the digestive system: Ingestion. Secretion. Mixing and movement. Digestion. Absorption. Excretion. What are the main cells in the digestive system?The gastrointestinal system has two classes of such cells, the islets of Langerhans in the pancreas and the enteroendocrine cells in the mucosal epithelium of the stomach and intestine.
