Correct Answer: Duodenum
✅ Correct Answer: C — Duodenum
The Duodenum is the first and shortest part of the small intestine that directly connects to the stomach. It receives partially digested food (chyme) from the stomach. In the duodenum, bile from the liver (via gallbladder) and pancreatic juice (from pancreas) are added to complete digestion of fats, proteins, and carbohydrates.
❌ Why other options are wrong:
• A. Jejunum — Jejunum is the second part of the small intestine (middle segment), not connected to the stomach; it is where most nutrient absorption occurs.
• B. Ileum — Ileum is the third and longest part of small intestine; it connects to the large intestine at the ileocecal valve, not to stomach.
• D. Caecum — Caecum is the first part of the large intestine; not connected to the stomach at all.
📝 Important Note: Small intestine has 3 parts: Duodenum (1st, 25 cm), Jejunum (2nd, 2.5 m), Ileum (3rd, 3.5 m). Duodenum = 'twelve' in Latin (12 finger-breadths long = 25cm). Most digestion happens in duodenum; most absorption in jejunum and ileum.
