What is "jejunum"?

The jejunum, a component of the small intestine, is responsible for further digestion and absorption of nutrients from food in the human body. Its inner lining is lined with specialized structures called villi, which increase the surface area for efficient nutrient absorption into the bloodstream. The jejunum plays a crucial role in the digestion and absorption of carbohydrates, proteins, and fats, contributing to overall nutrient assimilation and energy production.

Examples

1. The lower end of the duodenum is reconnected to the jejunum at a lower point.

2. The small intestine has three parts, the duodenum, the jejunum, and the ileum.

3. The next section is called the jejunum, and it has long projections on its surface, giving it a large surface area for absorption.

4. The top end of the second part - the jejunum - is pulled up and connected to the gastric pouch created in step 1.
