How does the human body digest food when in space?

The human body always digest food with the help from gravity to keep the food down but in space how?





How does food is digested if the food u eat floats in your stomach?





If possible can u please send a link about this question?|||Astronauts eat a kind of paste, it's basically stuff that your stomach doesn't need to break down|||Smooth muscles line your GI tract and push food along.|||Actually gravity is not needed. The food matter is moved along the digestive tract by muscle movement called peristalsis. The digestive tract (esophagus, stomach, small intestine, and large intestine) are not open pipes, but rather flattened tubes. They only expand when food is in them.
