3. What is the jejunum and where is it in the body?The jejunum is the middle part of the small intestine. It sits between the duodenum at the top and the ileum at the bottom.
4. Why is the jejunum called a food‑sorting superhero?Because it has thick walls, lots of folds, and many tiny finger‑like villi that give it a huge surface area. This lets it pick up and absorb almost all the nutrients from the food we eat.

Plicae Circulares: Large circular folds in the jejunal lining that increase surface area and slow food passage.
Malabsorption: A condition where the small intestine cannot properly absorb nutrients from food.
Enteral Nutrition: Providing nutrition directly into the gastrointestinal tract, often via a tube.
