Trachea
The fetal pig's liver is typically large in size and has a triangular shape. It is reddish-brown in color and has a smooth texture.
They Have Four Lobes
In the fetal pig, the esophagus leads to the stomach, and the trachea leads to the lungs.
A fetal pig's lungs are collapsed because they are filled with fluid while in the uterus. This allows for easier passage through the birth canal and prevents the lungs from being damaged during development. Once the pig is born and takes its first breath, the lungs expand and fill with air.
I just did this dissection on Friday. They're more smooth and firm. I'm 99% sure that this is because a fetus' lungs wouldn't have to expand and contract yet so it wouldn't take on that flexible, spongy texture. That's the answer I'm putting on my lab report anyway!
When the lungs do not function the backup respiratory system takes over the function of the lungs. This is true in a fetal pig.

Trachea
A fetal pig's lungs are similar to an adult's in the interior. The difference is that it is much smaller.
The fetal pig's liver is typically large in size and has a triangular shape. It is reddish-brown in color and has a smooth texture.

Fetal lungs are not functioning; no organism can start to breathe while immersed in amniotic fluid. Lungs only begin to function at birth.
The pleura cover and protect the lungs in a fetal pig.
In the fetal pig, the esophagus leads to the stomach, and the trachea leads to the lungs.
The trachea, heart, lungs, bronchial tubes, thyroid gland, and the larynx are found in the cavity of a fetal pig.
