Transcript of Esophagus

Digestive system
The esophagus receives food from your mouth when you swallow. The esophagus delivers food to your stomach.
The job of the esophagus starts with the act of swallowing takes place in the pharynx partly as a reflex and partly under voluntary control. The tongue and the soft part of the roof of the mouth push food into the pharynx (throat), which closes off the trachea. The food then enters the esophagus. The esophagus haves only one important function in the body - to carry food, liquids, and saliva from the mouth to the stomach. The stomach then acts as a container to start digestion and pump food and liquids into the intestines in a controlled process. Food can then be properly digested over time, and nutrients can be absorbed by the intestines

Can you live without it??
Yes. You can live without an esophagus. If you are eligible (having extremely serious problems with your esophagus) then you can have something called an esophagectomy. The esophagectomy will remove your esophagus.
diseases that affect
Barrett's Esophagus:
Barrett’s esophagus is a condition in which the tissue lining the esophagus is replaced by tissue that is similar to the intestinal lining. This process is called intestinal metaplasia. People with Barrett’s esophagus are at increased risk for a rare type of cancer called esophageal adenocarcinoma.
Fun Facts
An adult esophagus can range from 10-14 inches long
Once swallowed food takes about 7 seconds to get to the stomach
The esophagus is a tube that connects the pharynx (throat) with the stomach. When a person swallows, the muscular walls of the esophagus contract to push food down into the stomach. Glands in the lining of the esophagus produce mucus, which keeps the passageway moist and facilitates swallowing.

Esophageal Adenocarcinoma:
Esophageal cancer is cancer that occurs in the esophagus. Esophageal cancer usually begins in the cells that line the inside of the esophagus. Esophageal cancer can occur anywhere along the esophagus.
