Final answer:
The pyloric region is the part of the stomach that connects to the duodenum, it consists of the pyloric antrum and pyloric canal, and contains the pyloric sphincter that regulates the movement of chyme into the small intestine.
Step-by-step explanation:
The pyloric region of the stomach refers to the part that connects the stomach to the duodenum which is the first part of the small intestine. This region includes the wider portion called the pyloric antrum and the narrower portion called the pyloric canal.
The pyloric sphincter is a band of smooth muscle at the juncture between the stomach and the duodenum that controls the passage of partially digested food, known as chyme, into the small intestine.
During gastric emptying, the sphincter permits only liquids and small particles to pass, ensuring that the small intestine is not overwhelmed and can effectively digest and absorb nutrients. The churning and mixing actions in the pyloric region are facilitated by an inner oblique smooth muscle layer in the stomach's muscularis.
