Are there 5 sphincters in the digestive tract or 7?
Landon AndersonThere are six sphincters in the digestive tract, but some say five because they think that the cardiac sphincter is not a true sphincter valve.
You may have said five because of the cardiac sphincter. Some believe that this isn't a true sphincter valve, so they may not include it. The six sphincters are the upper esophageal sphincters (UES), the cardiac sphincter, the pyloric sphincters, the ileocecal sphincters, and the involuntary and voluntary a*** sphincters.
