Problem: The digestive system is the body system that digests food. It digest food in two ways, mechanically and chemically. Both help in the process of turning food into nutrients. The digestive system also eliminates solid food waste. The major organs of the digestive system include the mouth, esophagus, stomach, and small and large in- testines. These organs all work together to help you gain energy from the food you eat. Digestion starts in the mouth. When food is swallowed, it travels through the esophagus to the stomach. In the stomach, digestion continues and a small amount of absorption of nutrients takes place. Most chemical digestion and nearly all absorption of nutrients take place in the small intestine. This organ consists of three parts: duodenum, jejunum, and ileum. The large intestine is the last stop in the digestive system. This is where water is absorbed. The food not digested is released as waste.

Question: "Where does digestion begin and end?"

Answer: "The nose, the ears"

Problem: Here the omnibus came up, and I rode back to Manchester. The whole conversation took up very little more time than it will take to read it; but I thought it worth recording, as characteristic of the people now suffering in Lancashire from no fault of their own. I know the people well. The greatest number of them would starve themselves to that degree that they would not be of much more physical use in this world, before they would condescend to beg. But starving to death is hard work. What will winter bring to them when severe weather begins to tell upon constitutions lowered in tone by a starvation diet--a diet so different to what they have been used to when in work? What will the 1s. 6d. a-head weekly do for them in that hard time? If something more than this is not done for them, when more food, clothing, and fire are necessary to everybody, calamities may arise which will cost England a hundred times more than a sufficient relief--a relief worthy of those who are suffering, and of the nation they belong to--would have cost. In the meantime the cold wings of winter already begin to overshadow the land; and every day lost involves the lives, or the future usefulness, of thousands of our best population.

Question: "What was discovered about the nature of the Lancashire people from the conversations on the bus ride back to Manchester?"

Answer: "That this people would starve and succumb to the winter severity before condescending to beg"
