Here's a breakdown:
* Cardiac region: The top of the J, where the esophagus connects.
* Fundus: The rounded, dome-shaped portion that expands to hold food.
* Body: The central, main portion of the stomach.
* Pyloric region: The bottom of the J, which connects to the duodenum (the first part of the small intestine).
This J-shape allows for efficient digestion and storage of food.
