Video Transcription

Video Summary

Dr. Abegunde of John Stoker Hospital explains the anatomy and physiology of the small and large intestines. The small intestine, about 20-25 feet long, consists of the duodenum, jejunum, and ileum, responsible for digestion, nutrient absorption, and peristalsis. The large intestine (colon), 4-5 feet long, absorbs water, electrolytes, and forms waste for elimination. Key anatomical features include villi in the jejunum, ileocecal valve, and anal sphincters managing continence and defecation. He also discussed clinical tools like sigmoidoscopy and effects of GLP-1 drugs, which delay gastric emptying and impact digestion and endoscopic procedures.
