Pyloric antrum * 11. Pyloric canal * 12. Angular incisure * 13. Gastric canal * 14. Rugal folds. The pylorus is the furthest part of the stomach that connects to the duodenum. It is divided into two parts, the antrum, which connects to the body of the stomach, and the pyloric canal, which connects to the duodenum. [2]
The angular incisure (or angular notch) is a small notch on the stomach. It is located on the lesser curvature of the stomach near the pyloric end. Its location varies depending on how distended the stomach is. [1] The angular incisure is used as a separation point between the right and left portions of the stomach, the body and the pylorus. [2]
The stomach is involved in the gastric phase of digestion, following the cephalic phase in which the sight and smell of food and the act of chewing are stimuli. In the stomach a chemical breakdown of food takes place by means of secreted digestive enzymes and gastric acid. The stomach is located between the esophagus and the small intestine.
The anterior gastric branches of anterior vagal trunk are branches of the anterior vagal trunk which supply the stomach. [1]One long branch of it runs from the lesser curvature or parallel to it in lesser omentum as far as the pyloric antrum to fan out into branches in a way like the digits of a crow's foot to supply the pyloric antrum and the anterior wall of pyloric canal.
Surgery, consisting of excision of part of the lower stomach, also called antrectomy, is another option. [6] [16] Antrectomy is "the resection, or surgical removal, of a part of the stomach known as the antrum". [2] Laparoscopic surgery is possible in some cases, and as of 2003, was a "novel approach to treating watermelon stomach". [26]

The pylorus of the stomach has a thickened portion of the inner circular layer: the pyloric sphincter. Alone among the GI tract, the stomach has a third layer of muscular layer. This is the inner oblique layer and helps churn the chyme in the stomach.
Gastric outlet obstruction (GOO) is a medical condition where there is an obstruction at the level of the pylorus, which is the outlet of the stomach.Individuals with gastric outlet obstruction will often have recurrent vomiting of food that has accumulated in the stomach, but which cannot pass into the small intestine due to the obstruction.
