* O [[esfínter esofáxico superior]].
* The [[orbicularis oculi muscle]], a muscle around the [[human eye|eye]].
* O [[cardia]] (esfínter esofáxico inferior), na parte superior do [[estómago]]. Este esfínter impide que os contidos ácidos do estómago pasen ao esófago.
* The [[upper oesophageal sphincter]].
* O [[esfínter pilóricio]], na parte inferior do estómago.
* The [[cardia]] (lower esophageal sphincter), or cardiac sphincter, at the upper portion of the [[stomach]]. This sphincter prevents the [[acidic]] contents of the stomach from moving upward into the [[oesophagus]].
* O [[válvula ileocecal|esfínter ileocecal]] na unión do intestino delgado co groso, que impide o refluxo dos contidos do [[cego]] cara ao [[íleo]].
* The [[pyloric sphincter]], at the lower end of the stomach.
* O [[esfínter de Oddi]], que controla as secrecións do [[fígado]], [[páncreas]] e [[vesícula biliar]] ao [[duodeno]].
*The [[Ileocecal valve|ileocecal sphincter]] at the junction of the [[small intestine]] (ileum) and the [[large intestine]], which functions to limit the reflux of colonic contents back into the ileum.
* O [[esfínter uretral]], que controla a saída da [[urina]] do corpo.
* The [[sphincter of Oddi]], or Glisson's sphincter, controlling secretions from the [[liver]], [[pancreas]] and [[gall bladder]] into the [[duodenum]].
* O [[ano (anatomía)|ano]] posúe dous esfínteres ([[esfínter anal externo]] e [[esfínter anal interno]]), que controlan a saída das [[feces]] do corpo. O interno é involuntario e o externo é voluntario.
* The ''sphincter urethrae'', or [[urethral sphincter]], controlling the exit of [[urine]] from the body.

* At the [[anus]], there are two sphincters which control the exit of [[feces]] from the body (see [[Sphincter ani internus muscle|internal anal sphincter]] and [[Sphincter ani externus muscle|external anal sphincter]]). The inner sphincter is involuntary and the outer is voluntary.
