epiglottis
the epiglottis is the little flap that closes whenever you swallow to keep the food, water, spit, and whatever else you swallow from going into your lungs. It helps the digestive system because it keeps the things you eat and drink going down your esophagus (throat), which takes it to your stomach, and so on.
Peristalsis keeps your food going down into the digestive system.

Your epiglottis closes and opens in your throat. It's the part that causes gagging.
The epiglottis closes (to stop food going into the lungs) and the muscular walls contract to push the food down the oesophagus.
