The little folks who eat here do not sit at tables as you do. They are fastened to the walls, so they are always in the same places. Another name for this room is the “small intestine.” ELMER: I would like to see some of the little folks who eat there. How large are they? MOTHER: They are so very, _very_ small you could not see them unless you had a strong glass to help you. They stand up straight, like the soft, silky part of velvet or plush. They are called Villi. As the food comes in from the serving room, another helper, called In-tes´ti-nal Juice, takes any part which the other servants have not finished as it passed through their rooms, and thus digestion is complete. The Villi soak the food up as it passes them, as a plant draws water and food from the ground. HELEN: But how does it all get into the blood? MOTHER: I was just about to tell you that part of the story. You have seen little creeks, and you know they flow into larger ones, which form small rivers, and they, in turn, flow in some broad river toward the sea. So this creamy fluid which is sucked up by the Villi goes into tiny veins; these open into larger ones, till all flow in one stream about as big as a slate-pencil up to a large vein near the neck, and from there to the heart, where the stream is changed to blood, and is ready for use in the body. Part of the food takes another way to get to the heart. It goes first to the liver, which takes the part it needs, and the rest goes on to the heart. HELEN: Then all we eat finally gets into the blood. MOTHER: No; there is always some part that can not be used. Passing through the eating room the waste is carried into a garbage box, called the colon, which should be emptied every day. Now let us see if we can give the names of the different rooms a slice of bread passes through before it reaches the heart and becomes blood. ELMER: First, the passage, which is the mouth, down the steep stairs or gullet, through the stomach kitchen, through the serving room, the eating room, or small intestine, and from there straight to the heart, or else by another road through the liver to the same place. MOTHER: Very good. Now what juices make the bread ready to become blood. PERCY: First, the saliva in the mouth. AMY: And gastric juice in the stomach. HELEN: Then bile from the liver, and pan-cre-at´ic juice from the pancreas. ELMER: The last was the in-tes´tin-al juice. MOTHER: That is right, and let me tell you that in our bodies about twenty pounds of juices are made every day. Now I think we can remember that the food passes through five rooms, and it takes five juices to make it into blood. Two of the juice family, which have the long names, in-tes´tin-al and pan-cre-at´ic, are willing to work on all parts of the food. The others work chiefly on one part only. Saliva digests starch. Bile works on fats. Gastric juice takes the part which is called al-bu´men.
