The document compares parts of the digestive system and brain to parts of a school. The mouth is like the school entrance, the esophagus is like a hallway, and the liver gets rid of toxins like an office handles troublemakers. The stomach acts like an assembly for food and the pancreas breaks down food like the Breakfast Club kids. The small intestine carries food like pipes carry water, while the large intestine flushes waste like a toilet. The rectum acts as the body's exit. In the brain, the cerebrum stores information like a library, the cerebellum holds data like a lab, and the brain stem solves problems like a supervisor. The thalamus assists functions like a student activities coordinator
