1. Introduction
"Every bite you take begins a journey through a hidden tunnel inside you. This journey is longer, more complex, and more fascinating than most of us realize."


2. Mouth to Esophagus
"Digestion starts in the mouth — teeth shred, saliva softens, and enzymes like amylase break down starch. The bolus then travels through the pharynx and esophagus, guided by peristalsis."


3. Stomach
"In the stomach, hydrochloric acid and pepsin attack proteins while churning turns food into chyme. A mucus lining protects the stomach from dissolving itself, while sphincters control entry and exit."


4. Small Intestine
"The small intestine — duodenum, jejunum, ileum — is the true engine of absorption. Here, enzymes and bile break food into nutrients that pass into the blood and fuel every cell."


5. Large Intestine
"Undigested matter enters the cecum, then passes through ascending, transverse, descending, and sigmoid colon. Water is absorbed, and what remains forms waste in the rectum and anal canal."


6. Why It Matters
"Problems like acid reflux, IBS, or constipation all trace back to this tract. But beyond digestion, your gut influences mood, immunity, and even sleep — earning the name ‘second brain.’"


7. Conclusion (Takeaway)
"Your GI tract is not just a pipe — it’s the engine that keeps you alive. Next time you eat, remember: it’s not just food, it’s fuel for life."


8. Outro (Channel Close)
"So that’s it for today’s episode on the gastrointestinal tract. If you learned something new, share, like, and subscribe — and until next time, keep exploring the wonders of life."
