Video Summary

In this video, Dr. Femi Kassam discusses the small and large intestine. The small intestine is the longest part of the gastrointestinal (GI) tract, about 20-25 feet long. It continues to break down and digest food, while also absorbing nutrients and propelling digestive fluid to the large intestine. The small intestine is divided into three parts: duodenum, jejunum, and ileum. The duodenum has several sections, including the duodenal bulb, and receives contents from the stomach, bile ducts, and pancreas. The jejunum is responsible for absorbing carbs, fats, proteins, minerals, and some vitamins. The ileum absorbs bile salts, fat-soluble vitamins, and vitamin B12. The large intestine, also known as the colon, is about 4-5 feet long and absorbs water and electrolytes while eliminating solid waste. It consists of several segments, including the ascending colon, transverse colon, descending colon, sigmoid colon, rectum, and anus. Smooth muscle contractions facilitate the movement of fluid through the GI tract, and the rectum and anus control the release of stool. Dr. Kassam also briefly mentions pelvic dyssynergia and pelvic floor dysfunction, which can lead to constipation.
