Fetal Pig Dissection Lab Report

In this experiment, the external and internal structures of a sheep’s heart was examined and identified by dissection. To determine the functionality of a human heart since they are both mammals.

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.

3a. The function of the umbilical cord is to transport nutrients to the fetal pigs from the

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 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.

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.

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

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.

Depending on how developed the pig is, the testes can be found in different locations, but for the fetal pig, the testes can usually be found within the abdomen, specifically the inguinal canals. If not, they will be found in the scrotal sacs.

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

Gulp. Your favorite food, right in front of you. Mouth watering and eyes glued to the plate. A big inhale and the smell is even better than it looks. You just cannot wait to dive in and devour it, but how does one recognize what your favorite food is by just a sniff? Or what happens after you chew and swallow that meal? Mary Roach,“America’s funniest science writer”, will take you through the gates of the digestive system and explain everything one would ever want to know and more about what happens in the depths of the alimentary canal.

The purpose of the sheep brain dissection is to appreciate the complex structure of the brain in three dimensions. Also list, identify, and describe the important structures of the sheep brain and compare with those of the human brain. Materials: • Preserved sheep brain • Dissection tray • Scalpel • Scissors • Pins • Tweezers • Gloves • Safety glasses Procedure: • Obtain a preserved sheep brain from the bucket and place this on a dissection tray.

In spite of years of investigation in immunology, mechanisms that regulate the immune system in the bovine reproductive tract have received only little attention. This could be due to the complexities of the immune and endocrine system and also to the difficulties of conducting experiments in this field. The oviduct is an essential component of the female reproductive system that ensures successful reproduction [2]. Physiologically, the mammalian oviduct not only serves as a conduit for the transport of gametes and embryos, but also creates a proper environment that facilitates final gamete maturation, fertilization, and early embryo development. On the other hand, the oviduct is an open tube, provides a connection between ovary and uterine horn of either side passable for gametes and embryos or ascending pathological

The reproductive system is questionably the body system that is the most important influence on life as we know it. It is the w ay in which we procreate and ensure our existence as a species. However, the penis is only one part of the male reproductive system, which constitutes of a series responsible for generating, storing, and transporting the genetic material contained in the sperm cells. The main organs include: testicles (or testes), the epididymides, the vas deferens, the ejaculatory duct, the urethra, and the penis. Others are the scrotum, urogenital opening, and the prostate gland.
