Which part of the digestive system follows the duodenum?

The correct answer is the jejunum because it is the section of the small intestine that directly follows the duodenum. The digestive system is organized into specific segments that play distinct roles in the process of digestion and nutrient absorption. The duodenum, which is the first part of the small intestine, receives chyme from the stomach along with digestive juices from the pancreas and bile from the liver, initiating further digestion.

Following the duodenum, the jejunum continues the process of digestion and is primarily responsible for the absorption of nutrients. It is characterized by a larger diameter and numerous folds that increase its surface area, enhancing its ability to absorb vitamins, minerals, carbohydrates, and proteins.

In contrast, the ileum is the last portion of the small intestine, positioned after the jejunum, so it does not immediately follow the duodenum. The cecum is part of the large intestine and follows the ileum, while the stomach is the organ from which chyme is released into the duodenum and does not come after it in the sequence of digestion. Understanding the structure and function of these segments is essential for comprehending the overall process of digestion and absorption in the human body.
