The Esophagogastric Junction is a crucial part of the digestive system that connects the esophagus and the stomach. There are several synonyms that are used to refer to this important part of the human anatomy. For example, it is sometimes called the gastroesophageal junction, or simply the GE junction. It may also be referred to as the cardia, or the esophageal inlet, depending on the context. In medical terminology, it is often abbreviated as the EGJ. Regardless of what it is called, the Esophagogastric Junction plays a critical role in facilitating the flow of food and fluids from the esophagus into the stomach for further digestion and absorption.
