Jejunum

The jejunum is a segment of the small intestine located between the duodenum and the ileum. It is responsible for the absorption of nutrients from food and the passage of these nutrients into the bloodstream. The jejunum is about 2.5 meters long and is lined with villi, which are small finger-like projections. These villi increase the surface area of the jejunum to help with the absorption of nutrients. The jejunum also produces digestive enzymes and hormones, as well as mucus to lubricate the walls of the small intestine. The jejunum plays a crucial role in digestion and nutrient absorption. Nutrients such as vitamins, minerals, amino acids, and carbohydrates are broken down by enzymes and absorbed through the villi. From here, they are transferred to the bloodstream and distributed throughout the body. The jejunum also helps to regulate the balance of fluids and electrolytes in the body. The jejunum is part of the body’s digestive system, which is responsible for breaking down food and extracting nutrients that are then used to fuel the body. Without proper functioning of the jejunum, nutrients would not be properly absorbed and this could lead to malnutrition and poor health.
