Did You Know!
Your Digestive System Works Even When You’re Standing on Your Head
Gravity plays no role in moving food through your digestive system.
- Muscles in the esophagus use rhythmic contractions called peristalsis to push food downward—or upward, if needed.
- This means you could technically swallow and digest food while upside down, thanks to these powerful muscular waves.
- Astronauts in zero gravity rely entirely on this system to eat in space!
