How Long Is the Esophagus in the Digestive System?

How long is the esophagus in the digestive system? The esophagus is one of the first elements of the digestive system. It is the avenue that delivers food from the mouth to the stomach and it performs this work through a series of muscle contractions. So, how long is the esophagus and how long does the food have to travel to get from mouth to stomach?  The answer is debated, ranging from 23-30 centimeters.

According to Kid's Health.org, the esophagus is about 25 centimeters or 10 inches long.  Of course, getting a precise measure can be a little bit hard and evidence indicates that there are slight differences of opinion on the length of the esophagus. For example, according to information collected at Hypertextbook.com, the length of the esophagus may range from about 23-30 centimeters (or 10-12 inches in length).

The length of the esophagus is directly related to the height of the individual being measured, so the longer a person’s torso is, the longer the esophagus will be. 

Where Is Your Esophagus?

So, now you know how long the esophagus is, but where exactly is it?

• The full line of the digestive system starts with the mouth, considered a voluntary part of the system. When you eat something by putting it in your mouth, the pharynx prevents the food from entering the trachea. Once the food enters the esophagus the rest of the digestive process is considered involuntary. The stomach breaks the food down, and passes the nutrients into the small intestine, followed by the large intestine.
• The esophagus starts at the pharynx, which creates the intersection that separates the esophagus from the trachea and which is charged with the task of delivering air to the lungs during a breath.
• The esophagus ends at the cardiac opening of the stomach, where the food that is taken in is deposited to be broken down and then enter the small and large intestines. This is the final stretch of the digestive process.

So, now you know how long the esophagus is and you also know a bit more about digestion.
