Question

Quizplus · Accepted Answer

The primary function of the duodenum is to neutralize the acidic chyme (partially digested food) that enters the small intestine from the stomach. This is accomplished by the release of bicarbonate-rich fluids from the pancreas and liver. Neutralizing the acidic chyme allows enzymes from the pancreas and small intestine to function optimally, as they work best in a slightly alkaline environment.
