Disecting a Fetal Pig - Lab report

The procedure consisted of external anatomy. We were asked to exam several characteristics of the unborn pig which includes: determining the age of the fetus by measuring the body length from its snout to the rump, examine the amount of hair on body, examine the lips, nostrils, ears, eyes, feet, chest, stomach, nipples and sexual organs. The procedure also consisted of internal anatomy which includes the oral cavity, digestive system, circulatory system, respiratory system and urogenital system.

The first step upon obtaining the pig is to carefully examine the pig to determine its age and

After the 16-day lab, we have seen that many of the piglets decompose completely and some less than others. Our group believed

Dissecting animals helps students better understand the anatomy of, in this case, a fetal pig, and helps us prepare for what University has to offer, depending on what one will study.

2. Describe the functional anatomy of the duct system that conveys bile from the liver and digestive juice from the pancreas to the lumen of the

In my human anatomy teaching laboratories, the animal dissection experience generally emphasizes the isolation and

The cat dissection is the culminating component of this course because it solidifies our knowledge of anatomy and physiology by applying it to a tangible specimen. Mammalian dissection provides an experience that two dimensional diagrams are incapable of and serves as an indicator of whether entering a profession that involves the application of anatomy and physiology is suitable for students in this course. The cat dissection builds on the previous dissections of the fetal pigs and other individual structures throughout the year by applying them to a cat that shares similar well-developed organs and muscles found in human anatomy. I found value in recognizing the similarities and differences not only between human and cat anatomies, but also

The fetal pig dissection was helpful for one to understand the body and all of the body’s functions. The procedures helped the students precisely do the dissection correctly. The questions that were assigned helped the students have a deeper understanding of the pig’s body. 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.

Throughout the course of anatomy and physiology, my partner Lena Mitchell and I dissected a fetal pig today. The systems seen in the dissection were, the integumentary system, the respiratory system, the digestive system, the nervous system, the urinary system, the cardiovascular system and the male reproductive system. Also, I will go over the functions of the systems and the organs. I will talk about how it was dissecting the pig. Also, about what organs we took out, such as the heart, lungs, liver, kidney, small and large intestines, bladder, stomach, tongue, brain, eyeballs, and the reproductive organs.

Initially when seeing the fetal pigs, I was completely disgusted and figured I could not even look at them in the sink, let alone look at them when they are dissected. As my group pinned down the fetal pig and tied it’s limbs out of the way, I began to get more comfortable with the fact. As the dissection progressed, through observing the mouth and the thoracic cavity on the first day and the abdominal cavity on the second day, I became less grossed out. Observing the organs was interesting and I felt like it was a useful representation of what human organs are like, since it would not be ethical to use an actual human to dissect. I learned the difficulties that surgeons have to endure when performing a surgery. I can only imagine the high-pressure

To observe the anatomy and physiology of the fetal pig through dissection, the procedures for Labs 22-26 of the Biology 1107 Principles of Biology Laboratory Manual, 2017 were followed directly. This includes all materials and steps included (Lombard, Terry, Malinoski, 2017, Pages

Over the course of twenty-eight days, our criminal justice class performed an experiment that contained stillborn and natural death piglets. Thirteen piglets were put into certain scenarios such as: piglets hung in the air with and without clothes, on cement with and without clothes, in the grass with and without clothes, buried underneath dirt with and without clothes, burned with a torch, knife wound, bullet wound, and buried in a box with and without clothes. Over the course of this month, our group recorded on a daily basis the differences that occurred. To our amazement, we were able to find startling evidence as to how these piglets decomposed and the science matters behind it.

In courses such as biology, anatomy, and physiology, learning the anatomy of a human is imperative to learning about its functions and processes. Due to a lack of money, resources, and access, UConn cannot provide the use of a human cadaver for educational purposes. Since we lack actual human specimens, the next best thing is the fetal pig. The reasoning behind the choice of a fetal pig is because it is extremely similar to the anatomy of a human, with a few minor differences of course. A study at Cambridge

The next steps have already been taken by Professor Juan Carlos. They human pig chimera experiments began in 2015 in Spain and California. The research was funded by the San Antonio Catholic University of Murcia in Spain and the Moxie Foundation. Per the article, Juan Carlos, professor in gene expression laboratories “To date, most of our experiments have been conducted in California and Spain—under the supervision of local and national regulatory agencies”. The pig-human chimera has only been allowed to grow for four weeks after which it is sacrificed to abide by the guidelines with regulatory authorities which make the researchers eliminate both the surrogates (sow being impregnated) and embryos.
