The document compares the digestive system and brain to structures in a school. The digestive system is compared to areas of the school - the mouth is like the office doors, the esophagus is like hallways, the stomach is like the staff room, the small intestine is like the library, the large intestine is like plumbing, the rectum is like a toilet, the pancreas is like the principal, and the liver is like students. The brain is also compared to school areas - the cerebrum is like the office, the cerebellum is like teachers, the thalamus is like the computer lab, and the brain stem is like the PA system.
