At which vertebral level does the esophagus pass through the esophageal hiatus?

The esophagus passes through the esophageal hiatus at the T10 vertebral level. This anatomical detail is significant as it relates to the diaphragm's structure and function, where the esophageal hiatus is located.

At T10, the esophagus transitions from the thoracic cavity to the abdominal cavity, allowing it to connect with the stomach. This level is consistent with anatomical studies and imaging, which confirm the relationship between the diaphragm's openings and the passage of the esophagus.

Understanding this transition is crucial for comprehending how the esophagus functions and its interaction with surrounding structures, particularly during activities such as swallowing, which requires precise coordination of muscular contractions in this area.
