After passing through the stomach, food enters into what structure?

After food passes through the stomach, it enters the duodenum, which is the first section of the small intestine. The duodenum plays a critical role in digestion as it receives partially digested food known as chyme from the stomach. Additionally, bile from the liver and digestive enzymes from the pancreas are secreted into the duodenum to facilitate the breakdown of fats, carbohydrates, and proteins. This combination of chyme and digestive juices in the duodenum allows for further digestion and nutrient absorption to occur in the subsequent sections of the small intestine, namely the jejunum and ileum. Understanding this process is crucial for grasping the overall function of the gastrointestinal system in nutrient assimilation.
