The mother sow provides all the nutrients needed by the fetus until birth. Directly into the blood stream.
The human stomach is bigger than the fetal pig's. This of course is if the human is an adult human.
In the fetal pig, the esophageal opening is located dorsal to the glottis. The esophagus lies to the top of the stomach, in close proximity to the diaphragm.
The greenish substance in the stomach of a fetal pig is typically bile. Bile is produced by the liver and stored in the gallbladder before being released into the small intestine to aid in the digestion of fats.

In a fetal pig, the stomach is located in the upper part of the abdomen, below the diaphragm and between the esophagus and the small intestine. The inner surface of the fetal pig's stomach is lined with mucous membrane, which is composed of rugae (folds) that help expand the stomach to accommodate food and aid in digestion.

The inner wall of the stomach of the fetal pig is lined with gastric mucosa, which contains gastric pits leading to gastric glands. These gastric glands secrete enzymes and mucus that aid in digestion. The lining also has rugae, which are folds that allow for expansion of the stomach.
The thoracic duct of a fetal pig is used to transport food into the stomach. This is present before the development of the esophagus.
Controls passive from the esophagus into the stomach.
