The esophagus is thus one of the first components of the digestive system and the gastrointestinal tract. After food passes through the esophagus, it enters the stomach. [ 10 ] When food is being swallowed, the epiglottis moves backward to cover the larynx, preventing food from entering the trachea.
Esophagogastric junction outflow obstruction (EGJOO) is an esophageal motility disorder characterized by increased pressure where the esophagus connects to the stomach at the lower esophageal sphincter. EGJOO is diagnosed by esophageal manometry. However, EGJOO has a variety of etiologies; evaluating the cause of obstruction with additional ...
The upper gastrointestinal tract consists of the mouth, pharynx, esophagus, stomach, and duodenum. [13] The exact demarcation between the upper and lower tracts is the suspensory muscle of the duodenum. This differentiates the embryonic borders between the foregut and midgut, and is also the division commonly used by clinicians to describe gastrointestinal bleeding as being of either "upper ...
The gastrointestinal wall of the gastrointestinal tract is made up of four layers of specialised tissue. From the inner cavity of the gut (the lumen) outwards, these are the mucosa, the submucosa, the muscular layer and the serosa or adventitia. The mucosa is the innermost layer of the gastrointestinal tract. It surrounds the lumen of the tract and comes into direct contact with digested food ...
In human anatomy, the esophageal hiatus is an opening in the diaphragm through which the esophagus and the vagus nerve pass.
Esophageal dilation. Esophagal Bougie Dilator. Specialty. gastroenterology. [edit on Wikidata] Esophageal dilation or oesophageal dilatation (British English) is a therapeutic endoscopic procedure that enlarges the lumen of the esophagus. [1]
The respiratory tract is the subdivision of the respiratory system involved with the process of conducting air to the alveoli for the purposes of gas exchange in mammals. [1] The respiratory tract is lined with respiratory epithelium as respiratory mucosa. [2] Air is breathed in through the nose to the nasal cavity, where a layer of nasal mucosa acts as a filter and traps pollutants and other ...
Esophageal webs are thin 2–3 mm (0.08–0.12 in) membranes of normal esophageal tissue consisting of mucosa and submucosa that can partially protrude/obstruct the esophagus. They can be congenital or acquired. Congenital webs commonly appear in the middle and inferior third of the esophagus, and they are more likely to be circumferential with ...
