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.
