Question

What happens during swallowing? How air is kept separate from food in the digestive system?

Answer 1

When swallowing food it enters into your digestive system through your esophagus. Air that is taken into your system enters the windpipe. The epiglottis which is a flap located between the esophagus and windpipe covers the windpipe so that food does not enter it by mistake. This allows for food and air to stay separated in the digestive system.
