Esophagus - Esophagus

It is a tube measuring 20-25 cm in length, through which food passes by the action of the esophageal muscles pushing it from the throat to the stomach.
The esophagus is located behind the trachea and actually runs for part of its length in the neck, continuing downward toward the chest.

Various medical problems can arise when there is a disruption in the function of the esophagus. Among the common medical issues involving the esophagus are problems with the lower or upper esophageal sphincter. Esophageal problems also include inflammatory strictures of the esophagus, and the presence of a flat esophageal ring in the lower part of the esophagus.
Additionally, there may be disorders in the esophageal muscles affecting swallowing, tumors that interfere with swallowing, and impaired esophageal function. Destruction of the esophageal lining due to GERD (Reflux) is also a relevant issue. GERD (Gastroesophageal Reflux Disease) is a disorder in which acidic fluid from the stomach flows upward into the esophagus.
GERD can cause a sensation of heartburn in the chest, inflammation, and throat irritation. GERD damages the esophagus, creating ulcers and harming the esophageal lining. GERD is caused by issues with the lower esophageal sphincter, bacteria, hiatal hernia, and other factors.
