Pig Dissection Lab Report
Dissection of the Respiratory System of the Fetal Pig Inferior to the Larynx
Dissection is an art. We must carefully and accurately dissect the pig so we can identify all important parts. We must use caution when carrying and cleaning sharp dissection tools. Dissection must help us to get to figure out specific parts of the organ that we need. In general, dissection in biology lab will help us to see of how all the systems get together in an entire organism. We will get to see how they are all arranged spatially. We will also get a better idea of the texture of many organs that make up the pig's system. I chose to do the respiratory system because it is one of the easiest to describe, but nothing in the oral cavity because it's not very instructive, and we never do it in lab. Here are my twelve instructions for a fetal pig dissection. …show more content…
Retrieve a fetal pig In this first method, the great caution is recommended. It is required to retrieve a fetal pig from the bucket with large tongs, being careful to drain as much preservative as possible.
2. Stabilize the pig Place the pig ventral side up on a medium-sized dissection tray. Secure the pig to the tray using twine. Tie the twine to one of the pig’s front hooves. Wrap the twine behind the dissection tray and secure the second hoof. Do the same for the back hooves. In other words, place the pig on its back and tie it with its arms and legs stretched apart using twine.
3. Start of the dissection Beginning immediately superior to the umbilical cord, use large dissection scissors to make a small, V-shaped incision into the body cavity. Using the blunt side of the scissors, extend this incision in a U shape inferiorly around the umbilical cord to the pelvis and superiorly through the right side of the sternum to the
