a: Esophagus ~
b: a long slippery water slide
What:
"The esophagus is like a long slippery water slide. Muscles within your esophagus squeeze the food down towards your stomach. Whether you are standing up, laying down, or hanging upside down, you can safely swallow a bite of food, because the muscles within your esophagus know that their job is to send food in only one direction... towards your stomach."
