How is the pH of the stomach maintained?
Alkaline pancreatic juices are secreted into the small intestine and neutralize the acidic chyme.
As chyme moves through the duodenum does it become more acidic or more alkaline?
As chyme moves through the duodenum, it becomes less acidic and more alkaline. This is because the pancreas secretes bicarbonate ions into the duodenum, which helps neutralize the acidic chyme coming from the stomach. Additionally, the liver also contributes bile salts to the duodenum, which further helps to alkalize the chyme.
