a: digestive system ~
b: an automobile assembly line running backward
What:
"This efficient "factory" of the digestive system is like an automobile assembly line running backward, with the cars being taken to pieces bit by bit, instead of being built up. As it passes through the digestive system the whole mass of food that entered the mouth is reduced to its essential parts fatty acids, glucose, and amino acids and these disassembled products are absorbed into the blood."
