A fetal pig's lungs are similar to an adult's in the interior. The difference is that it is much smaller.
The left lung of a fetal pig has two lobes: the cranial lobe and the caudal lobe.
The right lung contains 4 lobes while the left lung contains 3
It looks like a clear glue that holds organs in place
right lung
The right lung of a fetal pig consists of the cranial, middle, and caudal lobes. The cranial lobe is the largest lobe and is further divided into cranial and caudal parts.
Yes, the aveloar sacs have not been inflated w/ air as the pig has never taken a breath. Niki C
The esophagus of a fetal pig, like many organs and body parts, looks very similar to that of a human. It is a long narrow tube, pinkish in color, with cilia lined in the inside (to help push down the food). Click on the link below for pictures of a fetal pig esophagus:
Mr. HUnt's class, right?
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.
Healthy lung tissue from an adult pig will float in formalin because there is a (relatively) large volume of air trapped in the alveolar sacs. Fetal pigs haven't taken a breath yet, so there is no air in the alveolar sacs. This is why the lung tissue from a fetal pig will sink in formalin. Incidently, this is also how medical examiners can determine if a child was stillborn or was born alive and then died - check to see if a section of lung from autopsy floats in the formalin.
The fetal pig has a four-chambered heart and not three-chambered. The chambers are divided between the upper and the lower chambers.
A fetal pig is fed by its mother through an umbilical cord just like a human fetus.
