Detailed explanation-1: -Structure. There are four main regions in the stomach: the cardia, fundus, body, and pylorus (Figure 23.4. 1). The cardia (or cardiac region) is the point where the esophagus connects to the stomach and through which food passes into the stomach.
Detailed explanation-2: -The fundus is the top, rounded area that lies to the left of the cardia. The body is the largest and main part of the stomach. This is where food is mixed and starts to break down. The antrum is the lower part of the stomach.
Detailed explanation-3: -Antrum: the lower portion (near the small intestine), where the food mixes with gastric juice. Pylorus: the last part of the stomach, which acts as a valve to control the emptying of the stomach contents into the small intestine.
Detailed explanation-4: -The pylorus is the bottom part of your stomach. It includes the pyloric sphincter. This ring of tissue controls when and how your stomach contents move to your small intestine.
