How many lobes does the left lung have in a fetal pig?
The left lung of a fetal pig has two lobes: the cranial lobe and the caudal lobe.
How many lobes does each lung of a fetal pig have?
The right lung contains 4 lobes while the left lung contains 3
What maintains the lung inflation during fetal developmnet?
Surfactant
What major differences should you notice between the left and right lung on a fetal pig?
right lung
What does a fetal pig lung looks like?
A fetal pig's lungs are similar to an adult's in the interior. The difference is that it is much smaller.
How many lobes the the left lung of the fetal pig have?
Pigs are mammals, and so have four-chambered hearts. Therefore, their left side has two chambers, a atrium and a ventricle, and the right side has the same. **Ignore the above answer as the person who answered apparently did not read the question. Specifically states LOBES OF THE LUNG, nothing to do with chambers of the heart.**
What are the 3 lobes in the right side of a lung in a fetal pig?
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.
Oxygenation of fetal blood occurs in the?
Oxygenation of fetal blood occurs in the placenta, where the mother's bloodstream and the fetus's bloodstream come into close proximity but do not mix. Oxygen from the mother's blood diffuses into the fetal blood, while carbon dioxide diffuses from the fetal blood into the mother's blood for elimination.
Why will the segment of lung tissue cut from the fetal pig sink when placed in water?
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.
Does fetal pig lung tissue sink in water?
Yes, the aveloar sacs have not been inflated w/ air as the pig has never taken a breath. Niki C
What are the two fetal circulation bypasses found in the fetal pig?
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.
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.
