Once Jack and his magical boat entered the Bicuspid Valve, the realization that he could not go back hit him. He began to worry as they walked through the thick-walled Left Ventricle. From here, because of his recent oxygenation, he could venture to places all over the prison. “Who goes there!” two strange voice shouted. Both men were standing under signs that read Aortic Semilunar and Atrioventricular Valves.
“My name is Atrioventricular Valve, but you can call me Lub. This is my brother Aortic Semilunar, but you can call him Dub. I will not let you pass unless you take a quick test. Failure means death. However, my brother will allow you to pass free of charge.” Jack was never good at tests so he opted for Dub’s door. After looking through the door expecting an entrance to some elaborate part of the jail, he saw a small hole in the wall.
“This is the Ascending Aorta. It is exactly 3.5 cm. After entering this you will notice a very branch like structure called the Arch of Aorta. At this intersection, if you choose correctly, you will end up in the Descending Aorta that will take you through the torso of the jail. This is all I can help you with for now.” “How am I supposed to fit through this hole?” Jack wondered. But, as he approached the door he was magically transported through the small gap.
“How did I… was that a wizard,” he thought. The adventure through the gap was exactly like Dub had explained. As he passed through the Aorta he noticed that he could decide when to turn or stop. He stopped several times until turning left into Abnormal Aorta. He assumed that his adventure would somehow end up past the Abdomen of the jail.
“How far do you wish to travel?” the weird wizard man said. “Where are you,” Jack said startled. “If you wish to travel deeper into the jail I could lead you through to the legs of the jail,” Dub said ignoring his question. “But once you reach this deep, you must leave my transportation and travel on your own.” Traveling through the jail, Jack began to wonder if it was worth it.
Then suddenly he stopped and was given an option to take a right or left at the Common Iliac Artery. “Left” he said. His journey continued through the External Iliac Artery where he saw the jails elimination method for liquids in the distance. Soon, he arrived at the Popliteal Artery and found himself in the legs of the jail. Now that he was abandoned by Dub’s magic he began to feel anxious again.
