Hypothesis I believe if we observe a fetal pig specimen, it will serve as a very helpful comparative tool in learning human anatomy because much of the fetal pig’s organ systems are very similar in anatomy and physiology to that of the human, as the pig and human are both mammals. From the fetal pig, we can gain an understanding of organ size, the relation between organ systems and how they function together as a whole.
Introduction Pigs are one of the most similar animals to humans, and can be analyzed to learn about the organ systems of the body. Both pigs and humans are mammals, omnivores, furless and featherless, and their fetuses receive nutrients from their mothers through the umbilical cord as they develop (Field). These

In the fetal pig, the heart was enclosed in a pericardial cavity, with the right and left lungs on each side of it (Freeman, et. al). The mediastinum, which includes the pericardium, the esophagus, the trachea, and other structures separates the thoracic cavity into right and left sides (Field, pg. 11). The muscular diaphragm separates the thoracic cavity from the abdominal pelvic cavity, where the digestive and urinary systems are located (Field p. 11). As we worked through the dissection we were able to observe each organ system individually and look deeper into all of the anatomical structures that play a role in its function.
The purpose of the dissection was to develop a deeper understanding of how the anatomy and physiology of organ systems are influenced by each other. The dissection allows us to take the knowledge we’ve learned from the fetal pig and to apply it in the context of the human body, as a valuable learning experience.
Materials and Procedures
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
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.
After the 16-day lab, we have seen that many of the piglets decompose completely and some less than others. Our group believed
Purpose: The purpose of this outline is to act as a guide and accompaniment to the Fetal Fibronectin Power Point as well as an aid for the Case Study learning activity.
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
Have you ever contemplated about the differences between a human and an animal’s body system or even more interesting, the anatomies of any two animals? Most important, people can explore how an animal sustains and grows itself. Also, you are able to learn animal management, which is useful for people working in a range of industries. Additionally, a body system consists of various organs which work together to carry out a special job, which is vital to living a healthy life. Most important, researching the anatomies of both, pigs and frogs, every system has its own composition of organs, functions, and its own purpose.
When society thinks about starfish, perch, chordate, and fetal pig they become extremely curious about how their bodies operate because of how they are made up. I will give a brief synopsis of all animals before going into major detail about them. According to the online website named dictionary.com, Starfish are any echinoderm of the class Asteroidea, having the body radially arranged, usually in the form of a star, with five or more rays or arms radiating from a central disk; asteroid (dictionary.com). It is known that a chordate is an animal belonging to the phylum Chordata, composed of true vertebrates and animals having a notochord (dictionary.com). According to research, a fetal pig is an animal in the phylum Chordata and class Mammalia (dictionary.com). A perch is known to be a certain kind of fish with very spiny fins (dictionary). Starfish, perch, chordate, and fetal pig are some very interesting animals that possess some exclusive qualities both similar and different.
All organisms in the world have a range of systems and organs in their body. Some organisms may share similar body systems while others have absolutely nothing in common. Several of those organisms include humans, pigs, crayfish, and earthworms. From their mushy, gushy organs to their soft, gentle skin, you may think, “How are humans and pigs possibly alike? Or a crayfish and an earthworm?” In many ways they may not be, but in other ways, they are very much alike. The body systems that will be compared and contrasted of these organisms are the nervous, circulatory, reproductive, muscular, integumentary, digestive, excretory, and skeletal systems.
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.
The dissection of fetal pigs in the laboratory is extremely important as pigs are complex organisms with an internal structure much similar to the human body. This provides students to with the opportunity to receive insight on how their bodies work. In addition, they will also be given the opportunity to learn about evolution through the dissection of a pig.
Sus scrofa, or the domestic pig is a member of the class Mammalia and the order Artiodactyla. Since we as humans are also a member of class Mammalia, we have a good deal in common biologically with pigs, although we might not like to think so. Since we have a good deal in common, it is very helpful for us to study these animals both anatomically and physiologically. We do this when we test medicines on pigs, perfect surgical procedures on pigs, and even when we used to use pig valves for replacements in human hearts. Thus the pig is a first-rate example of a mammal and the purpose of this lab is to recognize the specific similarities between the pig and ourselves as humans. To accomplish this we
The fetal pig was a great resource to dissect do to it’s similarities to the human body in which we study in anatomy class. In addition, the size of the organs make them easy to find and identify. Another reason we use the fetal pig is because many people do not think of pigs as pets. If people dissected cats, the mental damage done to the human dissecting it may scar them for life. It also may lead them a stray from the medical field. Fetal pigs have no real purpose, they are a product of the pork food industry. They are not intentionally bred for the purpose of dissection. Therefore, fetal pigs are the paramount of dissection. Fetal pigs are ultimately inexpensive.
Due to the fact that the fetal pig and the human being’s anatomy are extremely similar, with the exception of a few minor parts, the fetal pig will be a precise tool in learning about the anatomy of a human.
Well we dissected frogs, in the United States, dissection of frogs became common in college biology classes from the 1920s, and were gradually introduced at earlier stages of education. By 1988, some 75 to 80 percent of American high school biology students were participating in a frog dissection, with a trend towards introduction in elementary schools. The frogs are most commonly from the genus Rana. I learned that it's really gross on how we see frogs insides Other popular animals for high-school dissection at the time of that survey were, among vertebrates, fetal pigs, perch, and cats; and among invertebrates, earthworms, grasshoppers, crayfish, and starfish. About six million animals are (2016) dissected each year in United States high
Mother pigs spend most of their miserable lives in tiny gestation and farrowing crates so small that they can’t even turn around and forced to get pregnant over and over again, until their bodies can’t handle it anymore.. Males are either killed immediately, or castrated at a young age then kept only for their meat. Piglets, in general, are torn away from their mothers after only a few weeks, tails are chopped off, and the ends of their teeth are snipped off, then the spend days to weeks to months in cramped, crowded pens on slabs of filthy concrete until it gets decided what will happen to them.
