Hey y'all,
I was doing some research for work today and came across this wonderful little video on peristalsis. Watch it!

What struck me was how gentle peristalsis is, and also how gorgeous this gastric antrum is! Isn't this cool? Can you see how hard it is for constipated fecal material to get out now? Can you see how easy it might be to tear our internal organs up by eating the wrong foods and not drinking enough pure water?
