GI Tract in Health_Small_Large_Intestine

Pdf Summary

The document provides an overview of the gastrointestinal tract, focusing on the small and large intestines. The small intestine, comprising the duodenum, jejunum, and ileum, plays a key role in digestion, absorption of nutrients and water, and moving food along the gastrointestinal tract. The duodenum receives bile and pancreatic enzymes for food breakdown and nutrient absorption. The jejunum primarily absorbs nutrients like carbohydrates, fats, proteins, minerals, and vitamins. Meanwhile, the ileum continues nutrient absorption and specializes in bile salt and fat-soluble vitamin absorption.<br /><br />On the other hand, the large intestine, or colon, is responsible for water and electrolyte absorption, as well as elimination of solid wastes. Peristalsis, involving coordinated muscle contractions, facilitates the mixing and movement of content throughout the gastrointestinal tract. The rectum and anus control the release of stool, with the anus having both involuntary and voluntary sphincter control. Defecation involves relaxation of sphincters and descent of the pelvic floor muscles.<br /><br />Overall, the document emphasizes confidentiality and internal use of the information provided for educational purposes within the Sanofi organization. It also highlights the importance of adhering to approved labeling, regulations, and policies when discussing Sanofi products with customers.
