one. Which is the exception?
Retain food in each segment until mechanical actions is complete.
Allow measured amount of food to pass to next segment.
Synthesize dietary enzymes necessary for chemical digestion.
Prevent food from "backing up" into the preceding area. - CORRECT ANSWER -Synthesize dietary enzymes
necessary for chemical digestion.
