Dissections of a fetal pig are used to educate students around the world about the significance of the internal and external structures found within many organisms, thus contributing to a more profound understanding. These dissections provide visual education to students thereby providing them with knowledge that can be potentially be accessed in the future. The systems that are examined specifically are the respiratory, digestive, reproductive and the circulatory systems. The fetal pig are particularly useful due to the similar structures to that of a human. Furthermore, fetal pigs are used for dissection due to their relative size which can be managed in the classroom. The major organs examined during the dissection will be the heart, lungs,
Abstract: The objectives of this lab was to identify the internal and external anatomy of the fetal pig. The experiment was conducted by dissecting a fetal pig and actively seeing the external anatomy, Oral Cavity, Digestive System, Circulatory System, Respiratory System, Urogenital System, and Nervous System.

If a healthy female mouse gets pregnant, then excluding the weight she gains from simply growing, she will gain weight at a bit less than an exponential rate.
Alastair Norcross in his article “Puppies, Pigs, and People: Eating Meat and Marginal cases “expresses the moral dilemma based on factory farming. Norcross gives an example of a man named Fred. Fred has to torture puppies in order to be able to enjoy chocolate. This is because when puppies are brutally tortured and then brutally killed they release a chemical called cocoamone. This chemical enhances the taste of chocolate, so Fred is killing puppies for gustatory pleasure. Any morally sound person would be appalled at what Frank is doing to these puppies and that is the basis of Norcross’s article. He is arguing that raising animals on factory farms and what Fred is doing are both morally wrong, because in both cases we are brutally killing the
In Labs 22 through 26, my lab partner and I were assigned a fetal pig to perform a dissection on in order to understand anatomy, the study of an organism’s structure1, and physiology, the study of the functions and activities of a living organism2. Throughout these labs, we studied the structure of the fetal pig and performed experiments to understand four system processes: digestion, cardiovascular, respiratory, and excretory. Dissecting an organism, physically moving and seeing the different portions of the organism, especially of a fetal pig, is very important. This helps in the understanding of the skeletal structure and what series of physical and chemical processes the mammalian species body performs in order to survive.
What’s that Pig Outdoors? is a memoir whose name easily captures the attention of the potential reader. Moreover, the story of the title captures an important theme in the narrative, which is that being deaf can sometimes lead to humorous (and sometimes not so humorous) misunderstandings. Henry Kisor, the author of the memoir has been deaf since age three. Still, he grew up in the hearing world as a lip-reader, and does not separate himself from the hearing culture in the slightest. While his disability can lead to said misunderstandings, it hasn’t stopped Kisor from living his life the way he wants and feels is best for him.

Late one night a woman is driving home on the freeway, she’s hit head on by a drunk driver and killed. The man is charged with two accounts of murder; the woman, and her four-week-old embryo inside her. By law, everyone human being is guaranteed rights of life; born or unborn they are equal. The same law should be enforced concerning human embryonic stem cell research. Dr. James A. Thomson discovered stem cells in 1998 and they’ve intrigued scientist ever since. The stem cells themselves are derived from a three to four day old cluster of cells called a blastocyst and they are so coveted because they are pluripotent, meaning they can differentiate into any type of cell in the human body. Although embryonic stem cells show amazing potential to cure various disease such as cancer, congestive heart failure, Alzheimer’s and Parkinson’s disease, muscular dystrophies, and more. The methods by which they are obtained is controversial. Research on embryonic stem cells is unethical, unnecessary, and purely homicide.
The earliest human dissections date back to ancient Egypt and Greece where records of Anatomy were hand drawn and physiology was largely theorized. I find it fascinating that modern imaging technology allows us to view the body’s organs to see their functions and diagnose possible conditions or diseases. I first developed an interest in the field of Medical Sonography during my pregnancy with my first child. When I laid eyes upon the images of the growing little person inside of me, I knew I wanted to share in the joys of others as they experienced this as well (realizing this may not always be the case for others). Now returning to college, I have set my academic goals on the path towards this career. It wasn’t until I completed the Anatomy
The first step was to obtain the White Rat and to tie it in the supine position, anterior surface facing up in side the dissection pan. To tie the animal, we used butcher’s twine and secured the front and hinds legs using a “lasso” technique, careful not touch the sharp claws. To make the first insicion I had to locate the Xifoid Process of the rat (distal aspect of the sternum). Once I had located the Xifoid Process, I had to use forceps to pull the skin of the animal’s abdomen up and use the scissors to cut. The first incision is made from stem to sternum, cutting through the errectos abdomen muscle down to the groin. The second incision ion is perpendicular to the first below the diaphragm. Because of this technique we were able to open the abdominal cavity first. The third and forth incisions were made bilaterally above the legs. The last two incisions were made in upside down “V” shape on the collarbone, to expose the thoracic cavity. This dissection was both sharp, because of the use of the scissors and scapel and blunt because of the use of the probe and forceps to move organs and skin to expose other organs not yet identified.
Around 6th through the 2nd century many physicians would perform experiments on animals, just to satisfy their curiosity. They would study their anatomy to understand the differences between animals and humans. Galen of Pergamum (129-216 CE) was one of the first to ever dissected and vivisected animals for his testing. Vivisection is when resesrcher operate on living animals to study the animals body when it is a life. He would dissect sheeps, pigs, goats, and monkeys to better his surgical skills, and for his own research purposes. He discovered that arteries carry blood not air as many physicians believed over 400 years, and he also discovered the difference between arteries and veins. He learned more about nervous system by cutting animals
The very first thing our group did was prepare for the dissection. We watered off excess formaldehyde and dye on the outside of the rabbit, layered our work area with newspaper, and put on the provided protection. To begin dissection, we wanted the rabbit almost entirely skinless to expose the muscles underneath. In order to properly understand the innerworkings of a rabbit’s muscular system we referenced a small handbook and a further detailed cat manual. To prove knowledge of the muscular system; we proceeded to isolate and identify 20 muscles on both the ventral and ventral sides of the rabbit. After our examination of the outer layers, we broke into the thoracic cavity. The hardest challenge faced was the cracking of the rib cage; in order
Dissection kits are readily available and it’s an enjoyable and educational way to spend time with children. We purchased a complete dissection kit with nine preserved animal specimen, tool set, dissecting pan, and instructions on how to dissect. There are also videos on the internet that can be used as guidance. How fascinating it was to learn how muscles on a cow eye attached to the eyeball and at the same time how it compares with our eyes. Humans have 6 muscles attached to our eye ball, so ask the child to move their eyes in all directions and explain how it differs from a cow who only has four muscles to control their eyes. They can look up, down, left, and right. Explain to them that they cannot roll their eyes as we
Why should we use these innocent pigs to grow human organs. if 100,000 people are waiting for an organ, humans will go and use up 100,000 pigs and grow organs inside them. This idea of having that many pigs cut open, that is absolutely unethical. An animal should not go through a surgery just to help out a human. In many religions pigs are known to be unclean and sanitary. Also the recent H1N1 flu was transmitted by pigs, and if there was another
“What are you doing? Why are you doing that?”, these questions come from anyone and everyone who doesn’t know about showing livestock or from someone who's new to showing. If I am being totally honest I love being asked these types of questions! I don’t care if it's about why I feed my goats separate, or why they are clipped. I truly enjoy talking to the public and explaining why things happen for a certain way.
