A fetal pig is fed by its mother through an umbilical cord just like a human fetus.
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 two largest body cavities are the thoracic and abdominal cavities.
The lungs of a fetal pig do not contain air because a developing fetus receives oxygen and nutrients from the mother's bloodstream through the placenta, not from breathing air. Therefore, there is no need for the lungs to be inflated with air until birth when the piglet starts breathing independently.
The external intercostal muscles raise the ribs during inhalation, while the internal intercostal muscles lower the ribs during exhalation in a fetal pig.
There is a very good reason there is no food found in a fetal pig's stomach. The fetal pig was never born.
Fetal pigs are not as developed as an adult.
The trachea, heart, lungs, bronchial tubes, thyroid gland, and the larynx are found in the cavity of a fetal pig.

The epididymis in a fetal pig is responsible for producing sperm. It is located on one testicle in the fetal pig.
Controls passive from the esophagus into the stomach.
A fetal pig is an unborn pig used in schools for dissection. Therefore, a fetal pig doesn't have a life span, because they never actually lived.
gullbladder
In the fetal pig, the ovaries are located near the kidneys, closer to the dorsal side of the body. They are situated in the abdominal cavity, next to the kidneys and slightly towards the rear end of the pig.
Some key characteristics of fetal pigs include their small size, lack of fur, closed eyes and ears, underdeveloped limbs, and presence of umbilical cord attached to the placenta. Fetal pigs also have a developing skeletal structure, digestive system, and circulatory system.
The uterus keeps the trachea from collapsing in a fetal pig.
