Explanation:
The stomach is a J-shaped organ which is a part of the digestive system. The digestive system on one end is attached to the oesophagus and on the end to the small intestine.
The pylorus structure of the stomach is composed of thick muscles which help to mix or agitating the food in the stomach and controls the movement of the food to the duodenum which is the first part of the small intestine. The movement is controlled by the ring of muscles in the pylorus called pyloric sphincter.
Thus, Pylorus is the correct answer.
