The alimentary canal (also called the gastrointestinal [GI] tract) is made of several segments, some of which are mentioned in the question. The GI tract begins in the mouth, which secretes important digestive enzymes and performs mechanical digestion. Next is the esophagus, which is merely a vessel for transporting mashed up food from the mouth into the stomach. The stomach secretes acid and enzymes that continue the process of digestion. Next is the small intestine, which contains three parts: duodenum, jejunum, and ileum. Digestive enzymes are added in the duodenum by the pancreas. These enzymes act in all segments of the small intestine to aid digestion. Next is the colon, which is broken down into the ascending, transverse, descending, and sigmoid colon. The colon plays a somewhat minor role in absorption of digested particles and water. Then is the rectum and anus, which don't play a significant role in digestion or absorption, but rather contribute to continence and bowel movements.
The stomach is a connected to the esophagus and to the intestines. To reach the stomach for some medical procedures a scope is placed through the esophagus.
