Fetal pig dissection

Through the dissection of the fetal pig, we were able to compare and contrast the structure and functions of the organs to those of a human. We dissected the pig and observed all the exterior and interior structures. The fetal pig’s structure was almost identical to the human body. Since humans and pigs are both mammals, it can be very useful to study the fetal pig. We dissected the pig so that we should see the skeletal and organ structures that we learned about in class. Because pigs are also mammals, their structure is very similar to our own. By doing the dissection, we were able to physically see and touch the anatomy of the mammalian body rather seeing it solely in text form. This gives us a better idea of how the structures are intertwined to form the body as a whole. On the first day of the lab I observed the pig’s digestive system which includes the liver,small intestines, large intestine, and the pancreas. The liver was the largest organ in the fetal pig’s body and was shaped like small bean bag.

I was actually surprised when seeing the small intestine because I didn’t know it was bigger than the large intestine, it was a series of long brown tubes. The pancreas of a fetal pig is along the bottom of the stomach. The pancreas is a bumpy yellowish brown gland. Pigs teeth have to be sharp and pointed so they can chew their food well so it can be transferred to the stomach. The hard palate has to be hard and rippled so their food can be broken down easier, while it’s being chewed it will hit the hard palate and break down easily.The Epiglottis is a flap of skin that makes sure no food gets into the Respiratory tract. The lungs looked like a pair of bird wings, we pumped air into it and saw how it moved. The trachea was a long tube with 3 small hole’s in it.

The heart was the best part of the dissection because it looked like a series of tube’s put together to create it. I was surprised by how the aorta looked. The value of students dissecting a mammal, especially a pig is important because most students like to touch the thing they are dissecting. A pig gives us a chance to visualize and help us understand the systems in a mammal. My feeling about dissecting a pig is nervous because it is a real pig even though it is fetal. I feel like I will end up cutting the pig in the wrong spot. I was also excited to dissect the pig because I have never experienced this before and think it was a great learning experience for me.
