The main organs of the circulatory and respiratory systems were located here.
We removed the kidneys and sliced them open to obtain an internal view of the organ.įurthermore, we continued our incision upwards to view the thoracic cavity. The scrotum was located in order to verify the gender of the pig as a male. The liver, stomach, pancreas, and gallbladder were all clearly evident upon opening the abdominal cavity. The abdominal cavity was sliced open and we viewed the digestive, excretory, and reproductive systems of the animal. We then removed the forelimbs of the pig to allow for easier maneuvering of our dissection tools. This was expanded to view the soft and hard palate of the mouth. The dissection of the fetal pig begins with an incision to the jaw. There was no mutilation done to the animal, it was simply an exercise to observe and report the anatomy of the cadaver. The specimen was an unborn pig, which had died before birth, humanely extracted from the womb.
This dissection was conducted at New Tech High Coppell. The group believes that this lab was very beneficial because we got to do hands on activities that will enhance our understanding of not only the fetal pig but dissections as a whole. Lastly, we extracted the eye and took it apart that way we could see the lens and how everything worked together in the eye.Īll four days, we explored different systems and how everything worked together and discovered what the fetal pig really looked liked on the inside. Then we cut through the skull in order to examine in the brain.

On the last day we got to pull away the skin and tissue to examine the muscles, this was the nervous system and skeletal system. We got to see the tubes and how everything was connected together. By day three we got to explore the cardio and cut open the kidneys and heart. This allowed us to examine the soft and hard palate, as well as the digestive system. On day two, we finally started the dissection and began by cutting open the esophagus and the mouth.
On day one the group was to determine the sex of the pig, male, and that it had four toes and a few baby teeth. Dissections are very beneficial in the fact that you can have a deeper understanding and see things you would not see in a stimulation because stimulations would try to be perfect and not all animals are perfect. All members of our group participated in this lab because we all believe that dissections are beneficial to learning and can enhance what you are learning. Another question is, are dissections better than stimulations or vice versa. As a group we believe dissections are more beneficial than a stimulation online.ĭissections over the years have become a very controversial topic, in regards to is it right and should every student have to participate in dissections. The results we found were that hands on has a different way of being beneficial to students when learning about animals and dissection. We were also dissecting a fetal pig and learning about the digestive systems, cardio, kidneys, nervous and skeletal systems. Abstract During the Pig Dissection Lab we were determining if dissections were more beneficial than stimulations.
