Because the fetal lungs are inactive, the pulmonary circuit is bypassed. Half of the blood that enters the right atrium flows directly into the left atrium through the foramen ovale. The remainder flows from the right atrium to the right ventricle, then into the pulmonary trunk. The second bypass, the ductus arteriosus, transports the blood directly from the pulmonary artery into the aorta so it can be sent into systemic circulation.

Where can fetal pig diagrams be found?
Fetal pig diagrams can be found in most high school or "first" biology/zoologycollege, text books. There are many laboratory instruction manuals available also.
How does a fetal pig obtain energy?
A fetal pig is fed by its mother through an umbilical cord just like a human fetus.
What is the description of the inner wall of the stomach of the fetal pig?
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.
Identify two body cavities found in the fetal pig?
The two largest body cavities are the thoracic and abdominal cavities.
If a section of a lung is cut from a fetal pig and dropped in a glass of water it will sink as it contains no air. Give an explanation why the lung of a fetal pig would not contain air.?
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.
Why would you not expect to find food in the stomach of the 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.
Why are the ventricles of a fetal pig thinner than the walls found in the adult pig?
Fetal pigs are not as developed as an adult.
What organs are found in the thoracic cavity of a fetal pig?
The trachea, heart, lungs, bronchial tubes, thyroid gland, and the larynx are found in the cavity of a fetal pig.
What is the green debris found in the stomach of a fetal pig?
Meconium
What happens in fetal pig circulation?
In fetal pig circulation, blood is pumped from the heart to the lungs for oxygenation through the pulmonary artery and then returns to the heart via the pulmonary vein. Some blood bypasses the lungs through the ductus arteriosus and foramen ovale, ensuring that most of the blood circulation bypasses the non-functional lungs. This allows for the exchange of oxygen and nutrients between the mother's and fetal pig's blood through the placenta.
What is a rostrum of a fetal pig?
the rostrum is the snout of a fetal pig
What is the function of the epididymis of the fetal pig?
The epididymis in a fetal pig is responsible for producing sperm. It is located on one testicle in the fetal pig.
Where is the cardiac sphincter found in the fetal pig?
Controls passive from the esophagus into the stomach.
How long can a fetal pig live?
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.
What part of the fetal pig stores bile and lies underneath the fetal pig?
gullbladder
What is location of the ovaries of the fetal pig?
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.
Why is circulation to the lungs bypassed in fetal pigs?
It is bypassed because there is no need for the blood to go to the lungs and get "pick up" if the pig is dead.
