The pH of the small intestine, a crucial factor influencing digestive processes, varies along its length. Acidic chyme from the stomach enters the duodenum, where it encounters alkaline secretions from the pancreas and liver. This interplay neutralizes the chyme, creating a pH range between 5.5 and 7.0 in the proximal small intestine. As chyme progresses through the jejunum and ileum, the pH gradually increases, reaching approximately 7.4 in the distal ileum. The pH gradient facilitates enzyme activity, nutrient absorption, and microbial balance within the small intestine.
