Inside Sabrina's belly, we floated steadily in the murky fluids that filled her stomach. "I don't want to speak to soon... but I think she's finished eating..." The stomach garbled a response that told me she was full. The stomach lurched suddenly as more gas was emitted. Sabrina let out a tiny belch that to us was massive and shook the walls of her stomach as it came out. I leaned across the dashboard and looked out of the windscreen, unknowingly pressing another button. This time a small monitor rose from the dashboard and it displayed what looked to be a map of Sabrina's body, with us pinpointed in her stomach. "I really ought to stop leaning on these buttons... but this map could come in handy."<br/><br/>Sabrina's stomach groaned some more and an idea struck me. "Hmm, why don't we go a bit deeper and see what it's like?" I took the controls and submerged the bus under her stomach juices, exploring the vast depths of the mighty organ. It was dark and murky under here, and bits of digesting food floated past as I took the bus further into her stomach. It got darker and darker the deeper I went, the bus' headlights lighting up the floor of her stomach as we approached it. "Wow... this is incredible." I looked to my students, who STILL gave me nothing but blank, fear-filled expressions. "Fine, we'll go back up..." I piloted the bus back up to the surface of the stomach. It was a harder task moving upwards, as though there was suction pulling us downwards. When we surfaced I looked around, noticing something had changed. We were lower in the stomach than before we submerged...<br/><br/>"Um... does anybody feel like we were higher up before?" one kid said.<br/><br/>"You're right. Her stomach is draining into her small intestine... So. Seat belts  everyone! I've always wanted to say that!" I smiled. Miss Frizzle would be proud. "Looks like we're in for a bit of a ride."<br/><br/>The stomach started to drain as Sabrina relaxed. We were moving deeper into her abdominal region, to the intestines and beyond... The thought of this made me excited. The stomach was one thing, but her intestines were going to be great. Great? What was wrong with me, I was enjoying this all far too much. My musings were interrupted by a great sucking, draining sound as we were pulled closer and closer to an enormous sphincter at the bottom of Sabrina's stomach. The stomach garbled and groaned noisily with various liquidy sounds as we sailed closer to the path into her intestines. With a great wet "schluck" we were swallowed by the sphincter and passed into the duodenum. We were no longer in the stomach.<br/><br/>The bus was propelled into a gigantic tube, fully submerged. "Well class, here we are! The small intestine! Where food is absorbed into the bloodstream or passed on into the large intestine." The walls of the intestine were lined with villi, which were absorbing quantities of the vile gunk that had come from Sabrina's stomach. I cast my mind once again to the woman who we were exploring. Did she even know what had happened to us...? She was looking for the bus earlier on, but that was before she swallowed it without even realising. Would she have any idea of what we doing right now and where we were? How was she to know we were in her intestine? And even if she knew, what could she do about it? But the thing that bugged me most about her was that I didn't know her name... I needed a name, anything to stop calling her "that woman" or "the nice lady" and give her a proper name. Her real name. We didn't even know each other but we were closer than any other human beings had ever been to each other... For the foreseeable future she was going to be all I knew... The bus drifted along the small intestine, the headlights brightening the darkness.
