Fig. 3. Intragastric pH of Python molurus (N=7) as a function of time postfeeding (days). The insert illustrates the position of the pH electrode (attached to the rat's head) within the python's stomach. Note the decline in gastric pH following feeding and subsequent return after 7–9 days of digestion. The dotted portion of the x-axis signifies that the initial increase in pH upon completion of gastric digestion began 6–8 days postfeeding.
