Jejunum refers to the middle section of the small intestine.

The jejunum is a part of the small intestine in the digestive system, located between the duodenum and the ileum. In the fitness context, the jejunum plays a role in the absorption of nutrients from the food we eat, which is essential for maintaining a healthy body and supporting physical fitness.

During exercise, the jejunum receives increased blood flow to help deliver oxygen and nutrients to the muscles. This is important for providing energy and maintaining endurance during prolonged physical activity. The absorption of nutrients in the jejunum can also help support muscle recovery and growth after exercise.

Examples of nutrients that are absorbed in the jejunum include carbohydrates, proteins, fats, vitamins, and minerals. Maintaining a healthy jejunum and digestive system is important for overall physical health and fitness.
