There are many sphyncter muscles along the digestive tract, the pyloric, the duadenum, the anus etc. their function is kind of like a valve. relaxing a sphyncter is like opening a tap in order to let substances pass. Without them you would constantly cough up stomach acid. Your food would go straight through you improperly processed and at a rate such that your gall bladder would not be able to neutralise the acidity in your stomach contense, which would damage your intestines. You would not be able to hold feaces or urine. It would simply leak out. so yeah. pretty important.

This depends on what sphnicter muscle you are talking about, because there is more than one sphincter muscle in a cow.
ileocecal sphincter (valve)
The ring of muscle at the entrance to the stomach is the lower esophageal sphincter. This muscle is normally contracted to close the esophagus. At the lower end of the stomach food passes through the pyloric sphincter and into the duodenum of the small intestine.
a ring of muscle that controls the release of an organs products. EXAMPLE: Pyloric Sphincter controls release of chyme. Cardiac Sphincter controls deposition of food into the stomach from the esophagus. External Urethral Sphincter controls release of urine. External Anal Sphincter controls release of defecation.
cardiac sphincter; or gastroesophageal sphincter; or lower esophageal sphincter (LES); or esophageal sphincter from http://en.wikipedia.org/wiki/Cardia
