Question
Chapter 18, Problem 19RA
Summary Introduction
To review:
The regulation of gastric secretion of hydrochloric acid and pepsin during different phases of digestion.
Introduction:
The breakdown of large, insolublefood particles into small and soluble food molecules in order to absorb them through the blood plasma is called digestion. Digestion of food is completed within three phases, namely cephalic, gastric, and intestinal phase.
