Textbook Question
Chapter 35.3, Problem 1CSC
Stomach acid can be very destructive to the digestive tracts of people with bulimia, many of whom vomit several times daily. The strong acid in the stomach contents dissolves the protective enamel of teeth, making them extremely prone to decay. Stomach acid also damages tissues of the gums, throat, and esophagus. In extreme cases, the explosive pressure of repeated vomiting can tear or rupture the esophagus—a true medical emergency. Frequent vomiting weakens the stomach lining, allowing acid to attack the stomach wall, which may produce ulcers, and can even cause the stomach to rupture, a situation that can be fatal.
During normal digestion, food moves from the stomach to the small intestine—how is it processed there?

I do not understand it. An explanation leading to the correct answer would be helpful. Question: Michele M. has gastroesophageal reflux disease (GERD), a common source of chronic pain in the United States. GERD has many causes, but one of its causes is an overproduction of stomach acid. A medical professional suggests to Michele that she manage her GERD by drinking less coffee. Since Michele drinks many cups of coffee a day, she cannot imagine how she'll get by without it, and she comes to you to complain. She says the medical doctor told her that coffee stimulates the release of a hormone called "gastrin", and that she doesn't understand why some hormone would cause her to have so much extra stomach acid.
