+## Sphincters
+Sphincters are thickened regions of circular muscle that control the flow of contents at various points in the GI tract.
+- Contracted:
+	- Passageway closed
+	- Flow is restricted
+- Essential for normal digestion and absorption
+There are 3 main sphincters associated with digestion:
+1. Gastroesophageal/lower esophageal/cardiac - connects the esophagus to the stomach
+2. Pyloric - connects the stomach to the duodenum (small intestine)
+3. ileocecal valve - Connects the small intestine to the large intestine
+The upper esophageal sphincter is at the top of the esophagus (not as important).
