Question
Chapter 50.3, Problem 2R
Summary Introduction
To review:
The pH of the solution does not change when hormones that cause HCl (hydrochloric acid) secretion in the stomach are added to a ground-up piece of the stomach wall.
Introduction:
The major function of the stomach is to store the food consumed and provide it to the small intestine slowly so that the speed of digestion remain slower than the speed of food consumption. HCl is secreted in the stomach and helps to kill potential pathogens along with the break down of proteins.

With respect to pH, what would happen if the stomach emptied rapidly into the small intestine? Why would this be bad for digestion?
Our stomachs secrete hydrochloric acid. What functions does this hydrochloric acid serve?
What would happen to the human body if the liver, gall bladder, and pancreas excreted their digestive enzymes not at the beginning of the small intestine, but at the middle of the small intestine? Why?
