Esophagus (Oesophagus, Gullet)

The esophagus is a cylindrical tube located between the pharynx and the stomach, 22-30 cm long. The esophagus is lined with a mucous membrane; its submucosa contains numerous own glands, the secretion of which moistens food as it passes through the esophagus into the stomach. The muscular lining of the upper third of the esophagus is formed by striated muscle fibers; in the middle part they are gradually replaced by smooth myocytes; in the lower part they consist entirely of smooth myocytes. Muscle fibers and myocytes are located in two layers: the inner one is circular, the outer one is longitudinal. The muscular layer determines both the peristalsis of the esophagus and its constant tone (ed.). Diseases of the esophagus include: achalasia, carcinoma, hiatal hernia, esophageal varices, esophagitis and peptic ulcers. - Esophageal (oesophageal).

In modern medicine, medicine is one of the fastest growing branches of science. In this article we will look at the esophagus - a human organ that performs many important functions in the human body.

The esophagus is a cylindrical muscular tube running in the chest from the pharynx to the stomach, about 25-30 centimeters long. The alimentary canal passes food through itself and separates air from it. The peculiarity of the position of the organ is that it is located near the heart, because it is covered by the heart on the left side. Lymphatic and venous vessels extend from the esophageal tube on the inside. They form numerous branches around the walls of the digestive canal and penetrate into a variety of organs. The main function of the esophagus is swallowing, as well as carrying food and air along a small path and safe release in the stomach. The mucous tissue of the organ is covered with hydrochloric acid,
