it is because of the peristalsis
Esophagus
Peristalsis I think...
The esophagus is a muscular tube that connects the mouth to the stomach and is responsible for transporting food and liquids to the stomach for digestion.
The peristaltic movements are muscle contractions and its function on the esophagus is to push food down into the stomach and prevent it from going back into the esophagus.
The food moves in the food pipe because muscles push it down into the stomach.
The esophagus is a muscular tube that connects the throat to the stomach. When you swallow, muscles in the esophagus contract to push food down towards the stomach through a series of coordinated muscle movements called peristalsis. The esophageal sphincter at the lower end of the esophagus opens to allow food to enter the stomach and then closes to prevent backflow.
The esophagus is an organ that propels food from the mouth to the stomach not actuating on the digestive mechanism. Its task is to push forward the food or liquid you have eaten or drunk.
Peristalsis. The movement of muscles bringing the food to the stomach.
The esophagus carries boluses of food from the mouth to the stomach.
After passing through the pharynx, the food enters the esophagus, a muscular tube that connects the pharynx to the stomach. muscle contractions push the food through the esophagus and toward the stomach.
