Hello, I'm Bee Broccoli, coming to you from my favorite room in the house. I'm going to tell you all about how I got here.
It all started when "Mom" said vegetables must be eaten if dessert was desired, so I was doused in butter and salt, plucked into the mouth, and immediately beaten down by teeth and saliva. The job of the teeth was mechanical and the saliva was chemical. Digestion was in session from all sides.
After my work over in the mouth, I am forced into the esophagus in a series of swallows. Here comes some rowdy peristalsis, working what's left of me downward.
The esophagus forces me into the stomach, a nasty place. The high acid is a torturous form of chemical digestion, and the liver and his friends are throwing down all kinds of destructive juices. The churning, like an amusement park ride, is mechanical digestion that turns me into chyme. My fiber is about the only thing holding up.
