Question

Did you know? Your esophagus is 25 cm long and uses waves (peristalsis) to push food to the stomach — even if you're upside down. That's why astronauts can eat in zero-G. The tube lies directly behind the windpipe; that's why you shouldn't talk with a full mouth — risk of choking.

Je slokdarm (esophagus) is 25 cm lang en gebruikt golven (peristaltiek) om voedsel naar de maag te duwen — zelfs als je op je kop staat. Daarom kunnen astronauten in zwaartelos eten. De buis ligt direct achter de luchtpijp; daarom moet je niet praten met een volle mond — kans op verslikken.
