jejunum
[ dสษชหdสuห.nษm ]
anatomy
The jejunum is the second part of the small intestine that lies between the duodenum and the ileum. It is primarily responsible for the absorption of nutrients from digested food. The inner surface of the jejunum has numerous folds, or circular folds, called plicae circulares, which increase the surface area available for absorption. It is typically about 2.5 meters long and follows the duodenum. The jejunum plays a critical role in digestion and is essential for maintaining the body's nutritional needs.
Examples of usage
- The jejunum absorbs most of the nutrients from food.
- Surgeons must be careful not to damage the jejunum during operations.
- Problems in the jejunum can lead to malnutrition.
- The disease affected the lining of the jejunum.

Etymology
The term 'jejunum' originates from the Latin word 'jejunus', which means 'fasting' or 'hunger'. This etymology reflects the ancient observation that this part of the intestine is often found empty due to its role in nutrient absorption and the digestive process. The jejunum was named as such because it was often seen to be devoid of contents, especially in the context of autopsy and dissection of individuals who had not recently eaten. The historical study of human anatomy has roots in ancient civilizations, including Greek and Roman practices, where early anatomists delved into the structure and function of the intestines as part of understanding human physiology. Over time, the understanding of the jejunum and its significance in digestion evolved, leading to a greater appreciation of its essential functions in nutrition and health.
