The esophagus plays an important role in the digestion system.
The esophagus is an organ that is located in the upper part of the digestive tract and it is connected to the throat, or the pharynx, and then leads to the stomach.
The esophagus sometimes is called the “food pipe” because this is where food goes when a person eats or drinks.
The length of the esophagus is around 8 inches and when someone eats, a muscle in the esophagus contracts and it helps move the food down towards the stomach.
Relaxing and Contrasting Muscles
When a person swallows, there are muscles on the upper and lower part of the esophagus and these muscles relax and let the food or liquid pass down.
The muscles contract when they aren’t being used so that substances in the stomach cannot make their way up the esophagus.
When liquid food makes its way towards the stomach it goes through the esophagus. The esophagus is very strong, and it can pus the food down.
Most of a person’s saliva goes through the esophagus.
