Option 2 : Lower oesophageal sphincter
Concept:
- Gastro-esophageal reflux disease -> It is a disease characterised by frequent regurgitation of the stomach contents into the esophagus.
- The acidic nature of the gastric reflux often irritates the esophageal epithelium.
- Lifestyle changes can be done to manage and prevent GERD.
Explanation:
- Once the food is ingested from the mouth through peristalsis, the esophageal sphincter closes and prevents the movement of the food back towards the oral cavity.
- In case of GERD, gastric reflux regurgitates into the esophagus and damages the esophageal lining.
- Improper functioning of the lower esophageal sphincter leads to GERD.
- Duodenum is not affected in GERD as it lies below the stomach in the alimentary canal.
- Diaphragm is not affected in GERD
- Pylorus is not affected by GERD.
