cardiac sphincter

A muscular ring, called the cardiac sphincter, connects the stomach to the esophagus.

McCoy, next to him, looked a bit strained; it was an expression Kirk had seen before, on people trying to keep their cardiac sphincters in line.

You have a muscle called the cardiac sphincter that closes off your throat and esophogus from your stomach.

The cardia (lower esophageal sphincter), or cardiac sphincter, at the upper portion of the stomach.

When the shark deflates, the "bark" is produced by the pressurized air as it is released explosively through the cardiac sphincter of the stomach.

For example, the cardiac sphincter resides at the top of the stomach, to keep stomach acids and other stomach contents from pushing up and into the esophagus.

Hormone changes tend to relax the cardiac sphincter and this, together with pressure from the growing baby, can result in regurgitation of fluid plus a burning pain in the lower chest.

The cardia overlaps with but specifically does not contain the lower esophageal sphincter (LES) (also termed cardiac sphincter, gastroesophageal sphincter, and esophageal sphincter).

The junction between the esophagus and the stomach (the gastroesophageal junction or GE junction) is not actually considered a valve, although it is sometimes called the cardiac sphincter, cardia or cardias, it actually better resembles a structure.
