The stomach!
The pyloric sphincter valve.
The duodenum has a sphincter that controls the opening of the stomach to dump partially digested food into the small intestines. This sphincter can be weakened by stomach ulcers. After the duodenum, food stuffs continues through the small intestines where most digestion takes place.
It regulates the exit of partially digested food from the stomach and is in the lower region of the stomach
Yes, The pyloric sphincter valve regulates the exit of digested food from the stomach to the small intestine.
A sphincter is basically a hatch keeping stuff in and other stuff out of an organ such as the stomach. The pylorus is the muscle keeping the exit of the stomach shut, or opening it so that half-digested food may enter the duodenum to be digested further. The muscle ensures food can stay in the stomach long enough, and not flow right on through without being modified long enough by the stomach acids and digestive enzymes. It also regulates the amount of stuff that goes through.
The cardiac sphincter is located at the top of the stomach and controls the direction of food passing through the esophagus so that no food will re enter the esophagus. The Pyloric sphincter stops bile and digested food from entering the stomach, this valve is located at the bottom of the stomach.
Sphincters are circumferential muscles that can relax or constrict to regulate the passage of material through a particular area. The stomach is bound by two sphincters in humans: the lower esophageal sphincter that keep stomach acid in the stomach and the pyloric sphincter that regulates the flow of food in the stomach into the duodenum.

The circular ring of muscle located at the entrance and exit of the stomach is referred to as a "sphincter" - the one at the entrance to the stomach is referred to as the cardiac sphincter, and the one at the exit of the stomach to the small intestines is referred to as the pyloric sphincter.
