Here's why:
* Chyme is the partially digested food that passes from the stomach to the small intestine.
* Gastric acid in the stomach, which has a pH of around 1.5-2.0, plays a significant role in breaking down food.
* As chyme moves through the small intestine, pancreatic secretions rich in bicarbonate neutralize the acidity, increasing the pH.
* The specific pH of chyme depends on factors such as the type of food consumed, the amount of gastric acid produced, and the rate of gastric emptying.
Key takeaway: Chyme is acidic, but its pH changes as it travels through the digestive system.
