edit: “muscles moving things along” doesn’t quite add up for me, especially in the context of the stomach. On anatomical charts of the human body, the passage connecting the stomach to the small intestine is either on the right or left *bottom* portion of the stomach. Lets assume its on the right, bottom side of my stomach: if I am laying on my left side, that passage is then at the *top* of my stomach.
This concept could be applied to the entire G.I. tract as it winds through my body – if I am laying on my side, food and liquid would at some point have to move not just down, but also UP.
How do muscles do all of that, especially in what is essentially a pool of liquid (stomach) when the only way out is above everything?
