Small and Large Intestine in Health

Video Transcription

Video Summary

The lecture reviews the small and large intestines and their functions. The small intestine—duodenum, jejunum, and ileum—digests food and absorbs nutrients, with pancreatic enzymes and bile entering the duodenum. Villi increase absorptive surface area; the ileum absorbs bile salts and vitamins B12, A, D, E, and K. The large intestine absorbs water and electrolytes and forms and eliminates stool. Peristalsis moves contents through the gut. The rectum stores stool, while the internal and external anal sphincters and puborectalis muscle help maintain continence and coordinate defecation.
