Esophageal disease

The esophagus sometimes develops various natural disorders that weaken its ability to perform its action, that is, swallowing. All sorts of instrument diseases and diseases of complicity occur in it, in which hot, cold and hard tumors are formed; among instrument diseases, blockages most often occur in it; they occur either as a result of external pressure emanating from a displaced vertebra or from a tumor in a neighboring organ, or due to swelling of the esophagus itself or the muscle that holds it upright. Associated diseases that occur in the esophagus include bleeding and hemorrhage due to rupture of a vessel.

Know that swallowing is carried out by the esophagus with the help of a retractive force, which draws in food by the action of longitudinal fibers; it is assisted by transverse fibers, holding swallowed food behind and pressing it down. Vomiting is also carried out by the action of the esophagus, but swallowing is easier, since this movement occurs naturally with the help of two membranes, one of which has longitudinal fibers, and the other, enclosing it, is equipped with transverse fibers. As for vomiting, this is a movement that does not occur naturally, an action that is performed with the help of only one enveloping, squeezing membrane.
