Aus Dornheim Anatomy
The inferior constriction (constrictio phrenica) results from the esophagus passing through the diaphragm at the beginning of the pars abdominalis and is called diaphragmatic constriction. Functional closure of the esophagus is ensured by the adjacent longitudinal tension of the musculature and by the veins of the esophageal wall. At rest (outside the act of swallowing), the lower part of the esophagus (pars abdominalis) is permanently closed.
