Video Summary

In this video, Dr. Callaway discusses the different parts and functions of the gastrointestinal (GI) tract, focusing on the small intestines and the large intestines or colon. She explains that the small intestines are responsible for digesting food and absorbing nutrients, while the colon's job is to compact waste and eliminate it. The small intestines are comprised of three parts: the duodenum, the jejunum, and the ileum. Dr. Callaway also mentions that diseases often occur in the duodenum and biopsies are taken for diagnosis. The small intestines are about 20 to 25 feet long. The duodenum receives food from the stomach and helps with digestion and absorption. The jejunum and ileum continue the process of absorption. The large intestines or colon absorb water and electrolytes from the compacted waste and eliminate it. Dr. Callaway explains that motility, or the movement of food through the GI tract, is important for digestion and explains peristalsis, which is the wave-like contraction of muscles that helps propel food. She also mentions that various motility disorders can affect the GI tract at different points. The video concludes with a question and answer session.
