A pig dissection lab is a common activity in high school biology classes that allows students to learn about the anatomy and physiology of a mammal. The pig is often used as a model for human anatomy because it has many similar organs and body systems.
The dissection begins with the identification of external features, such as the eyes, ears, nose, and mouth. Students then proceed to make a longitudinal incision down the midline of the pig to expose the internal organs.
The first organ that is typically encountered is the diaphragm, which separates the thoracic cavity from the abdominal cavity. The thoracic cavity contains the heart, lungs, and trachea, while the abdominal cavity contains the liver, stomach, intestines, and other organs.
As the dissection continues, students can identify the various organs and their functions. The heart, for example, is a muscular organ that pumps blood throughout the body, while the lungs are responsible for gas exchange, taking in oxygen and releasing carbon dioxide. The liver is a vital organ that plays a role in digestion and detoxification, and the stomach is where digestion of food begins.
In addition to learning about the anatomy and functions of the various organs, students can also learn about the circulatory, respiratory, and digestive systems. The circulatory system consists of the heart, blood vessels, and blood, and is responsible for transporting oxygen and nutrients to the body's cells. The respiratory system includes the lungs and airways, and is responsible for exchanging gases with the environment. The digestive system includes the mouth, esophagus, stomach, intestines, and anus, and is responsible for breaking down food and absorbing nutrients.
A pig dissection lab is a hands-on learning experience that allows students to explore the inner workings of a mammal and gain a better understanding of the human body. It is an important part of a biology education and can help students to develop critical thinking and problem-solving skills.
Pig Dissection Lab report
Also, this greater knowledge of the excretory system in a pig can be translated to the human body. Locate the two umbilical arteries that carry blood from the fetal pig to the placenta, and the single umbilical vein that delivers nutrient-rich blood back to the fetal pig. Yes, our fetal pig contained hair on his chin, had eyelashes, and had a tongue as well. We need to know each part where there are and their functions so when we start open our pigs that we do not mess it at all. Laboratory Report: Dissection of Pig Heart 1. Remove this sac to expose the heart.
The hampshire pig has a wide forehead with a good amount of space Pig Dissection Lab Report 801 Words 4 Pages On this pig dissection we started off by taking the pig out of the bag letting some of the fluid drain off back into the bag so we will not get it everywhere. The second pig saw buckets of flower, he decided to purchase it. The heart was turned over. This, now oxygenated, blood then flows through the pulmonary veins into the left atrium, and continues to the left ventricle through the bicuspid valve, where it is then pumped to the aorta to be pumped to the bodies tissues. The next part of our dissection we pinched the belly of the pig and cut a portion of skin inferior to the diaphragm creating a window to expose all the superficial organs of the abdomen. The procedures helped the students precisely do the dissection correctly.
The body of the uterus and the uterine horns is located behind the urinary bladder, and the ovaries were located on bilateral sides of the pelvic which lye below the kidneys. Introduction Dissections over the years have become a very controversial topic, in regards to is it right and should every student have to participate in dissections. As you examine each anatomical structure, try to memorize its name, appearance, and location. The students were able to make comparisons of this dissected pig heart to that of a human, leading to a stronger grasp on the human circulatory system. The students who had the female fetal pig were to dissect the heart which we then viewed the hearts region the superior vena cava, inferior vena cava, aorta, pulmonary truck, brachiocephalic vein, subclavian vein, brachiocephalic artery, and the subclavian artery was observed. It is separated from the right atrium by the septum, and from the left ventricle by the bicuspid mitral valve. Having similar functions, the valve on the left side is the bicuspid valve Lane, 2010a.
The pericardium membrane covering the heart was thin and hard to be removed. The results we found were that hands on has a different way of being beneficial to students when learning about animals and dissection. A solution to this error would be to again, dissect a preserved heart that is injected with dye. Gouvernel faced issues with being different from the rest of the students and Dac found it difficult to accept the lifestyle and culture of his grandmother. Laboratory Report: Dissection of Pig Heart 1.
Aorta is principal vessel. Other main structures in the right side, including the inferior vena cava, the superior vena cave and the tricuspid valve were located. We cut with the use of scissors detaching our left lung of our pig. But what about that party that John and Lorraine had. All these organs were easily assessed, and viewed in amazement. The purpose of this dissection was to provide us with a basic understanding of how an autopsy is conducted.
With John and Lorraine delivered home in a police car. This is a typical call we arrive at Animal Control. For… Ethical Issue The use of animals in biomedical research has a lengthy history. This distracted the students from becoming fully invested in the dissection due to breaks they had to take from dissecting, and even breaks to exit the classroom. We also identitified the sex of our fetal pig, and upon observation at the base of the umbilical cord we determined the sex was a male. As well as major part of product testing in many companies.
Pigs are mammals Hampshire Pig Research Paper 547 Words 3 Pages The hampshire pig has experienced many changes in evolving from the wild pig to hampshire pig. You should now be able to peel open the left and right flaps of the ventral body wall like a book. We saw first hand the inner workings of a mammal. We concluded our dissection for the evening to be continued next week. These new skills will become very beneficial for other labs in the future.
This often occurs with the pig fully conscious, which, obviously, results in a tremendous amount of suffering for the burnt pig Singer 1995: 150-151. The heart was turned so that the front or ventral side was facing the observers. Wash out the cavities of the pig in a sink if needed to remove any brownish material mainly bile and clotted blood while being careful to keep the organs in place. Rui Lu Pig kidney dissection Purpose By cutting open the pig kidney, to figure out the following parts: capsule, cortex, medulla, pyramid, papilla, column, major calyx, minor calyx, hilus, renal artery, renal vein, pelvis, sinus and ureter of the kidney. Secure the pig to the tray using twine. The rectum and anal opening of the pig was observed.
Procedures of examining the external structure Lane, 2010a 1. The liver, stomach, pancreas, and gallbladder were all clearly evident upon opening the abdominal cavity. This allowed us to get a view of the len of the eye. Recently I had the opportunity of helping, and at the same time being educated by one of the members of this unfortunate group. We also located and viewed the facial nerve which was a thin pale band like structure. The heart was pushed open. Experiments were conducted by manipulating the independent variable, adding pork liver in two of the polony treatments, and observing differences between the test samples and the control sample.
Oxygenated blood can enter the left atrium via the pulmonary veins. This would allow the students to have an even better understanding of the kidney and the excretion system. Then we cut through the skull in order to examine in the brain. The three flaps or leaflets on the tricuspid valve were counted and observed. They were able to tie in their learning from classroom discussions and textbook work into a first-hand learning experience with a pig heart.
