Cаmerоn, Piper, аnd Alаna are in a nutritiоn cоurse together and are reviewing what they’ve learned about digestion. They are discussing where digestion starts in the body and the path that food takes through the GI tract. Cameron says digestion starts in the pharynx since that is where food passes when swallowed. Piper thinks digestion starts in the mouth when the food is being chewed, and Alana believes that digestion starts in the small intestine since absorption cannot occur until the food is mixed with pancreatic enzymes. Which student is correct?
