Detailed explanation-1: -The stomach: At the end of the esophagus is a muscular ring or valve called a sphincter (SFINK-ter). The sphincter lets food enter the stomach, then squeezes shut to keep food and liquids from flowing back up into the esophagus.
Detailed explanation-2: -The lower esophageal sphincter (LES), also termed the cardiac sphincter and cardioesophageal sphincter, is located slightly more than an inch (about 3 cm) proximally from where the esophagus meets the stomach.
Detailed explanation-3: -In humans and many other animals, the stomach is located between the esophagus and the small intestine.
Detailed explanation-4: -The duodenum is the first part of the small intestine. It is located between the stomach and the middle part of the small intestine, or jejunum.
