This dissection also helped the students become familiar with some of the organs in the body like the liver, heart, and intestines. All in all, this dissection was helpful in learning all about the body. During this lab, many procedures needed to be completed. This dissection took a week. The dissection required many steps. This dissection required an understanding of how the body works and what the organs look like. The fetal pig dissection was helpful in learning all about the body. In order to perform this dissection correctly, certain materials were needed. A dissecting tray, scalpel, bag, scissors, and fetal pig were needed. The dissecting tray is used to put the pig inside and to make all of the incisions. A scalpel is used to make all of the incisions. The bag is used to put the fetal pig inside when the day is over. Scissors are used to cut any excess skin off. Lastly, the fetal pig is used to learn more about the human body. Day 1

On first day of dissecting, many procedures need to be completed. Walk into the lab and put on goggles and gloves. Proceed to the lab bench assigned. One student from each bench go to the teacher and get a fetal pig in the dissecting tray with a scalpel inside. Once the pig is back at the lab bench, examine the outside of the fetal pig. Write down the fetal pig’s skin color, skin texture, length of the pig, gestational term, sex of the pig, and any markings on the pig. Once all of the information is written down, one is ready to dissect. Make a cut through the skin and around the rib cage. Questions are ready to be answered now. Write down what is seen after the first cut, if the cut was difficult to cut through, the amount of layers of skin shown, if there is a layer of fat, what the muscles look like, and if any blood vessels are visible. After the basic questions are answered, answer if the sternum was able to be cut easily, what the sternum felt like, and if the sternum made a cracking sound. After all the questions are answered, make the next cut. Cut in between the skin/muscles and the rib cage on each side. If needed, the ribs can be cut out. This may make working in the Thoracic cavity easier. After the incision is made, questions need to be answered. Answer what the bones of the fetal pig look like, what the consistency of the bones are like, how many ribs are shown, what the color of the bones are, and what the knee joint looks like. The last question was if one was able to find the spine and if that part was found, how many vertebrae’s there are. Look at the muscle that was being cut through. Answer what the muscles look like, if one can see the difference between smooth, skeletal and cardiac, and if there are differences between the muscles found around the rib cage and the muscles in the legs and then explain the differences. After all of these questions are answered, day one is over. Carefully put the fetal pig into a bag, close the bag, and place the fetal pig inside of the refrigerator. One must then give the scalpel to the teacher. After those steps are finished, clean up the lab bench, take the gloves and goggles off, and walk back into the classroom. Day 2

Start day two of the dissection. Walk into the lab, put on a pair of goggles and gloves and walk back to the lab bench. Get the fetal pig out of the refrigerator and bring that back to the lab bench. Once the fetal pig is back at the lab bench, carefully take the pig out of the bag and place the pig inside of the dissecting tray. Go to the teacher, get a scalpel, and go back to the lab bench. Open up the pig’s skin on the stomach and look inside. Cut off excess skin to be able to get a better view. After one can visibly see inside of the...
