The term “cardial orifice” refers to a specific anatomical structure within the human body, particularly within the digestive system. The cardial orifice is located at the junction between the esophagus (food pipe) and the stomach. It is more commonly known as the lower esophageal sphincter (LES).
The cardial orifice or lower esophageal sphincter serves as a gateway between the esophagus and the stomach. Its primary function is to regulate the passage of food and liquids from the esophagus into the stomach and prevent the backflow of stomach contents back into the esophagus.
The LES is a ring-like muscular structure that contracts and relaxes to allow the proper movement of food. During swallowing, the LES relaxes, allowing the food to enter the stomach. It then contracts tightly to prevent the gastric acid and partially digested food from going back up into the esophagus, also known as gastroesophageal reflux (GER).
Disorders or dysfunctions of the cardial orifice can result in various gastrointestinal issues. For example, if the LES becomes weak or fails to close properly, it can lead to acid reflux or gastroesophageal reflux disease (GERD). This condition causes symptoms such as heartburn, regurgitation, chest pain, and difficulty swallowing.
In summary, the cardial orifice, also known as the lower esophageal sphincter, is a crucial structure that helps regulate the movement of food from the esophagus to the stomach and prevents the backflow of stomach contents.
