Does digestion work the same inside our bodies in space? Each time I see an astronaut about to eat in space and watch their food floating around I wonder if it still moves through the body the same as it does under the gravity conditions on earth. Is there no gravity impact on that process? I know pressure has a direct relationship with gravity but how does that influence impact our bodies internally?

Scientists were very worried about exactly this problem which is part of why we sent up animals to see what would happen.
