Find the adrenal glands: small, white bands of tissue on the top, inside edge of each kidney. Using a scalpel, follow the directions in this step, making . Aorta, kidney, liver, posterior vena cava, renal artery, renal vein, spleen, ureter, urinary bladder. It forms into the skin, nervous system, enamel of the teeth, lining of the intestine, mammary and sweat glands, hoofs, and hair. trailer [12], The prenatal development of the fetus includes all the tissue and organ development. I found the trachea to be wider, stronger, and it had a bumpy surface. The offspring follows the same classification of its parents which is domain: Eukarya, phylum: Chordata, class: Mammalia, order: Carnivora, and family: Canidae. Fetal Pig Programming - An Emerging Concept with Possible Implications for Swine Reproductive Performance. While pictures are useful for learning the anatomy of the fetal pig, be careful with only memorizing drawings. Livestock Update. Figure 14. The ectoderm has a greater role in the development of the fetus. Click here to go to the Dissection Protocol for both the Pig and Sheep kidneys. The rate at which these folds increase is negatively related to fetus size. When breathing, air passes through the nasal passages to the pharynx. In some people, the foramen ovale does not close up. Esophagus, larynx, trachea, bronchus, and lung. Below the oropharynx, the laryngopharynx leads to the opening of the larynx and esophagus. The pancreas is located dorsal and posterior to the stomach. The renal artery passes blood from the aorta to the kidney. There is a shunt between the wall of the right and left atrium called the foramen ovale. Open the jaw wide enough so that the glottis and epiglottis are exposed. Position the pig in the dissection pan with its ventral surface up. It houses bacteria used to digest plant materials such as cellulose. The fetal pig's digestive organs are well developed before birth, although it does not ingest food. Wolxy s(Vulpes Lupus) are the offspring of a red fox and a gray wolf. Contraction of the diaphragm forces air into the lungs. Locate the two kidneys in the abdominal cavity. Extend a single cut along the midline of the ventral surface of the animal to about 2 cm from the chin. 0000001332 00000 n Urinary (Renal) System Anatomy Male and Female Fetal Pig Dissection (HD Quality) Pop Up Biology 1.08K subscribers Subscribe 18K views 2 years ago To see the structures more clearly, be sure. 13.1: Respiratory System and Pig Dissection, { "13.1.01:_Fetal_Pig_Dissection_Lab" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "13.1.02:_Fetal_Pig_Dissection_Lab_(Instructor_Materials_Preparation)" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "13.1.03:_Reading-_Fetal_Pig_Dissection" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "13.1.04:_Cardiovascular_and_Respiratory_Systems_Lab" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "13.1.05:_Cardiovascular_and_Respiratory_Systems_Lab_(Instructor_Materials_Preparation)" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "13.01:_Respiratory_System_and_Pig_Dissection" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, https://bio.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fbio.libretexts.org%2FCourses%2FLumen_Learning%2FBook%253A_Biology_II_Laboratory_Manual_(Lumen)%2F13%253A_Module_10-_Cardiovascular%2F13.01%253A_Respiratory_System_and_Pig_Dissection%2F13.1.03%253A_Reading-_Fetal_Pig_Dissection, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), 13.1.2: Fetal Pig Dissection Lab (Instructor Materials Preparation), 13.1.4: Cardiovascular and Respiratory Systems Lab, CC BY-NC-SA: Attribution-NonCommercial-ShareAlike, status page at https://status.libretexts.org. Fourthly, fetal pigs are easy to dissect because of their soft tissue and incompletely developed bones that are still made of cartilage. Colon, horn of uterus, ovary, urinary bladder, Figure 50. The fetal pig that you will dissect has been injected with a colored latex (rubber) compound. 41A, RS : 633-634 Urinalysis (OMIT : sediment analysis); 628-631 Test : prepared "pathologic" urine specimens. Aorta, colon, kidney, posterior vena cava, renal artery, renal vein, testicular artery, testis, umbilical artery, ureter, urinary bladder, vas deferens. The forelegs of the frog and fetal pig are also considered a part of the anterior end. Creator. Download. The thyroid gland is darker and lies between the posterior ends of the two lobes of the thymus gland. The spleen is an elongate, flattened, brownish organ that extends along the posterior part of the stomach ventral to (above) the pancreas. There are several reasons for this, the main reason being that pigs, like humans, are mammals. However, clear urine production and discharge could not be confirmed, suggesting the possibility of urinary retention. Here's a diagram of circulation in a fetal pig: Image courtesy of OpenWetWare. 0000007704 00000 n The word urogenital refers to an opening that serves both the urinary (excretory) and the reproductive systems. Instead, it gains much needed nutrition from the mother pig via the umbilical cord. Several different pig dissections were used to obtain the photographs below. Aorta, aortic arch, left atrium, brachiocephalic artery, ductus arteriosus, lung, pulmonary artery, pulmonary trunk, left subclavian artery, Figure 35. In a fetus, the placenta is the source of oxygen and nutrients, and also removes metabolic wastes from the blood. . Figure 46. This condition, called patent foramen ovale, can result in serious health problems. Please read through all of Dissection Exercise #7. The base of the liver opens into the hepatic hilum, which is but the entrance area of the omentum (omentum) lower with the portal vein, hepatic artery and hepatic duct outlet. Aortic arch, left atrium, brachiocephalic artery, left common carotid artery, right common carotid artery, larynx, pulmonary trunk, left subclavian artery, right subclavian artery, left ventricle. 0000017679 00000 n Find the posterior part of the large intestine called the rectum and observe that it leads to the anus. The swelling behind the hind legs of the fetal pig[23] is the scrotum. Anatomy of the Urinary System : Ex. In this area the inferior vena relates receives liver and the hepatic veins. Heart, liver, lung, posterior vena cava, thymus, thyroid. D *This dissection . 1. define urea, peritoneum, urine, urinary bladder, homologous, ovulation, semen, inguinal hernia, vasectomy, nephron, meningitis 2. locate the organs of the reproductive system in a fetal pig 3. describe and give the functions of the reproductive system 4. explain the importance of the reproductive systems to a living mammal Description. A similar cut is made on the other side. The fetal pig urinary tract is relatively developed and easy to locate during dissection. Language links are at the top of the page across from the title. This dissection lab is a great no-prep activity for Biology and Anatomy students to learn about the anatomy and physiology of the kidney. The pulmonary artery is capable of delivering a large amount of blood to the lungs but the lungs are not needed to oxygenate the blood of a fetus, so most of the blood is diverted to the aorta. For example, when a dancer lands after a vertical jump, the force exerted on the head by the neck must exceed the heads weight by enough to cause the head to slow down and come to rest. The pyramids are the smooth, discolored structures located in the inner core of the kidney, above the pelvis. The upper part gives rise to the urinary bladder . Use the probe to peel away muscle tissue until the thymus gland on each side of the trachea is exposed. Figure 36. These tubes are the ureters. Insert one blade of scissors through the body wall on one side of the umbilical cord and cut posteriorly to the base of the leg as shown in the first photograph below. Aorta, colon (large intestine), diaphragm, heart, kidney, lung, renal artery, posterior vena cava, renal vein, small intestine, spleen, stomach, ureter. The hard palate and soft palate separate the nasal and oral cavities. The epiglottis projects up through the soft palate into a region called thenasopharynx. They are slightly more expensive, but well worth it, as the solution is non-toxic, doesn't smell as bad (which is a plus. 4.9. You will need to cut through the musculature and the joint that holds the lower jaw to the skull. Obtain a fetal pig and identify the structures listed in the first photograph. The fetal pig that you will dissect has been injected with a colored latex (rubber) compound. Many other factors, including depth of placental folds, are also responsible for these interactions. Dissection instructions, student lab worksheets, and diagrams are all included. In order for digestion to occur, the fetal pig would have to ingest food. Your finished cut will be anterior to the navel and along each side of the navel. Blood vessels that branch from the aorta carry blood to most of the body. The cecum is large in herbivores but much of it has been lost during evolution in humans. 0000003210 00000 n Below: hard palate, soft palate, glottis, epiglottis, tongue. (1) 3. Extend a single cut along the midline of the ventral surface of the animal to about 2 cm. Find the bile duct that leads to the small intestine. The spleen is an elongate, flattened, brownish organ that extends along the posterior part of the stomach ventral to (above) the pancreas. The width of the placental folds decreases until day 85 of gestation. Use a probe to separate the two lobes of the thymus gland and to further separate the musculature over the trachea. <<0A8475290F23494581369D9CD21F7021>]>> Locate the cecum, a blind pouch where the small intestine joins the large intestine. It contains the nitrogenous wastes, ions, drugs and other materials filtered from the blood by the kidneys. Female: injection site, nipples, umbilical cord, Figure 2. Note that you will need to remove some of the pyramids to see the remaining structures, which lie underneath. Obtain a sheep kidney from those provided. 0000002242 00000 n Fetal Pig - Vessels Near the Heart. Dissected, narrated and labeled by Dr. Robyn Nearn, DVM. This answer is: .

I use Carolina's Perfect Solution 10 - 13 inch Fetal Pigs, in a pail. Next, the urine goes into the ureters, followed by the bladder and urethra before exiting. Find the bile duct that leads to the small intestine. This structure stores bile produced by the liver. Retrieved July 16, 2009 from. Find the posterior part of the large intestine called the rectum and observe that it leads to the anus. From there, the urine can be excreted. Also any dissection manual from freshman biology lab for fetal pigs. Nebraska Scientific (2009). Fetal pigs are the unborn piglets of sows that were killed by the meat-packing industry. The renal medulla is the region of the kidney containing the calyces, pyramids, columns, and papillae. The pericardium is a membrane that surrounds the heart and lines the pericardial cavity. Krauthammer claims that organs should be harvested only from the dead and not the living because only dead people can be considered commodities. Copyright 2023 IPL.org All rights reserved. 0000005494 00000 n The arteries have been filled with red latex and the veins with blue. The size of the fetal pig depends on the time allowed for the mother to gestate: No studies have found significant data regarding the mother swines diet and fetal pig survival rate. Use the photographs below to identify its sex. With the left lung removed, the heart can be pushed to the right side to reveal the aorta and other blood vessels shown in figures 3342. Large intestine, liver, small intestine, spleen, and stomach. The first lymphatic organ to become present is the thymus. Lab 12. In this article R. Alta Charo states that we have a right to use fetal tissue for research and therapy (Fetal Tissue, 1) The article goes into how a lot of people find this to be a moral issue and a matter of the conscience and explains how the antiabortion activist that dont agree with the research are actually benefitting from the fetal tissue. Fetal pigs are the unborn piglets of sows that were killed by the meat-packing industry. The following words will be used to help identify the location of structures. Nebraska Swine Reports. [16] In 1995 it was concluded by the International Agency for Research on Cancer (IARC) that formaldehyde is a carcinogen for humans.[17]. An adequate amount of floor space allowed the higher percentage of gilts to reach puberty sooner than those gilts who had less floor space. The pig's kidney was much less significant in size compared to the kidney of the sheep. The illustrated, print manual contains 55 A&P exercises to be completed in the lab . Below: esophagus, larynx, trachea, bronchus, lungs. Def: Main organs of the urinary system, 2 bean shaped organs, Def: Two thin retroperitorial tubes the connect the kidneys to the urinary bladder, Def: Arteries that supply the kidneys with blood, Chapter 1- The Science of Biology; Biology 00, Human Anatomy and Physiology Laboratory Manual, Bio 208 Lab (Urinary System and Urinalysis). You will then dissect a sheep kidney in order to observe the internal structures of a kidney. The cecum is large in herbivores but much of it has been lost during evolution in humans. Your finished cut will be anterior to the navel and along each side of the navel. Please watch the video at the following link to support your understanding of the material in the lab. It houses bacteria used to digest plant materials such as cellulose. Repeat this with the back leg. Use figures 14 below to identify its sex. The pulmonary artery is capable of delivering a large amount of blood to the lungs but the lungs are not needed to oxygenate the blood of a fetus, so most of the blood is diverted to the aorta. The arteries have been filled with red latex and the veins with blue. Figure 44. The next system I dissected was the respiratory system. Use your pig and also a pig of the opposite sex to identify the structures in the photographs below. The Urogenital system is the organs of the pig associated with urinary excretion and reproduction. 40, RS 623-626 Gross Anatomy of the Urinary System, 614-617 Microscopic Anatomy 617-621 Dissection of the Fetal Pig Urinary System, 749 : Lab 11. Figures 29 and 30 summarize the circulatory system of a mammal. Continue cutting from the anterior end of this cut so that it resembles an upside-down U. Background: Despite the importance of the pyelocalyceal system in the pig as an experimental model, there is little information about this particular anatomical subject. In other words, cells make up tissues, tissues make up organs, organs make up organ systems, and organ systems make an organism. 0000000016 00000 n Fetal Pig Practice Quiz - ll in blanks and self check. Make a longitudinal incision through the kidney, so that you cut it into two equal halves. Fetal Pigs in Biology. The shape of these kidneys are both bean like. It is also flat and full of muscle. The arteries have been filled with red latex and the veins with blue. [22] The uterus, which becomes the vagina, is located where the fallopian tubes meet. [3][4], A systematic review concluded that students taught using non-animal methods demonstrated superior understanding of complex biological processes, increased learning efficiency, and increased examination results. [5] It also reported that students confidence and satisfaction increased as did their preparedness for laboratories and their information-retrieval and communication abilities. Follow the steps below to complete the dissection of the Fetal Pig Urinary System. Large intestine, liver, small intestine, spleen, and stomach.

It contains the vocal cords. The flap of body wall that contains the navel can be folded posteriorly to reveal the internal organs of the abdomen. 4. Pigs, as a mammalian species, provide a good specimen for the study of physiological systems and processes due to the similarities between many pig and human organs. As a result, a structure shown in one photograph may look different than the same structure shown in another photograph. How to calculate apparent weight in water? Figure 12. The large hard structure attached to the trachea is the larynx. Observe how the diaphragm attaches to the body wall and separates the abdominal cavity from the lung (pleural) and heart (pericardial) cavities (Photographs below). Several different pig dissections were used to obtain the photographs below. Development of new technologies that can improve the efficiency of nitrogen (N) utilization in ruminants, and that are effective and safe, has . Use a scalpel to cut the sides of the mouth so that the bottom jaw can be opened for easier viewing (see figure 11). After food is digested and nutrients are absorbed, the food follows through the large intestine and solid wastes are excreted through the anus. The large hard structure attached to the trachea is the larynx. The diagrams below summarize the circulatory system of a mammal. The incision can be seen in the first photograph below. bFAQhA"Ahj)AwbYk3g^GDffzpnq|!gdszd2QHLW!Tx[Ql)Y,Sy~q!n![a]?K+Q;ej5 oAVrK1!|3#1'E) m^gs%2 qW+ ne%$kp@@P1SU{P{WHrjN5 |#nETi q|o5Bo`$7AJ*?1:*|lVD9&g'J]+9biV)hI>wAW"QzHb:n_}voHf96Bujy>{ %ADAnO-Z/>;`A`~m{Cq].gqzv1G[-O0 The correlation, however, is not statistically different. Journal of Animal Science. Fetal Pig Internal Practical. The astounding part of the living organisms have led us some understanding of the awe-inspiring structure of every life from as small as 0.0000001 to over 0.1. External iliac artery, kidney, large intestine, posterior vena cava, renal vein, small intestine, testis, umbilical artery, ureter, urinary bladder. The drawing below shows some of the major arteries that carry blood to the body. Mesenteries serve to connect the organs of the fetal pig together. It contains a lubricating fluid and isolates the heart from body movements such as the expansion and contraction of the nearby pleural (lung) cavity. The male's internal reproductive system has two scrotal sacs, which depending on the age of the fetal pig may or may not have developed testes. Description: The kidneys are located on the lumbar region of the body cavity, their main function is the production of urine and the filtering waste from blood, and balance body fluids. Variation in voice is often the first sign of throat cancer, since the vocal cords are often the first portion of the throat that cancer will develop within. The anatomy of a fetal pig is similar to that of the adult pig in various aspects. 1 Jun 2009. This is one handout for use during the embryo pig dissection. Use your pig and also a pig of the opposite sex to identify the structures in the photographs below. A similar cut is made on the other side. The pericardium is a membrane that surrounds the heart and lines the pericardial cavity. In the photograph below, the heart and blood vessels of the neck region have been removed so that the trachea can be seen more clearly. [25] Similar to the female system, it may be difficult to identify all parts. In the fetal pig however, the metabolic wastes are sent back to the mother through the umbilical cord where the mother excretes the wastes. Fetal Pig Dissection. (. The efficiency at which nutrients are transferred dictates the health and growth of the fetus. It forms the muscles and connective tissues of the body, blood vessels and cells, the skeleton, kidneys, adrenal glands, heart, and the reproductive organs. The placenta is used as a means of transferring nutrients from the mother to the fetus. Figure 32. (in larger male fetal pigs) at the base of the urethra, close to the junction with the bladder:- . Expectoration is basically when you are coughing up mucus and saliva. This diagram shows that the ductus arteriosus connects the pulmonary artery to the aorta and diverts blood that would otherwise go to the lungs. Texas A&M College of Veterinary Medicine & Biomedical Sciences The urogenital sinus is a part of the human body only present in the development of the urinary and reproductive organs.It is the ventral part of the cloaca, formed after the cloaca separates from the anal canal during the fourth to seventh weeks of development.. You have already seen how the esophagus leads from the pharynx through the neck region. Both the kidney of the pig, and the kidney of the sheep shared similar structures and shapes. Seminal vesicle, testis, ureter, urinary bladder, vas deferens, Figure 53. Open the jaw wide enough so that the glottis and epiglottis are exposed. J. Anat. From the pharynx, it passes through the glottis to the trachea. 0000006318 00000 n Use the probe to peel away muscle tissue until the thymus gland on each side of the trachea is exposed. The first branch of the aorta is the brachiocephalic artery. This allows blood to pass directly from the right to left atrium.
