Pig dissection labs are a common occurrence in high school biology classrooms, where students have the opportunity to learn about the anatomy and physiology of animals by dissecting a pig's body. While some students may find the experience educational and interesting, others may have reservations about the ethical implications of dissection.
One argument in favor of pig dissection labs is that they provide a hands-on learning experience that allows students to better understand the inner workings of an animal's body. By dissecting a pig, students can gain a deeper understanding of the various organs, muscles, and systems that make up an animal's body and how they function together. This type of experiential learning can be more engaging and effective than simply reading about animal anatomy in a textbook.
However, there are also valid ethical concerns surrounding pig dissection labs. Some people argue that it is wrong to use animals as objects for human education, especially when there are alternative methods of learning available. There are also concerns about where the pigs used for dissection come from and how they were treated prior to being used in the lab. Some schools have started to use alternative methods such as computer simulations or videos of dissections to avoid these ethical issues.
Ultimately, the decision to use pig dissection labs in education is a complex one that requires weighing the benefits of experiential learning against ethical concerns. While there are certainly valid arguments on both sides, it is important for schools and educators to consider all perspectives and make an informed decision about the use of pig dissection in their classrooms.
Fetal Pig Dissection Lab
The first part of the systemic arterial circuit is the aorta, which soon branches out to supply various regions of the body. In mammals, the coelom is divided into two main cavities: the thoracic cavity, which contains the lungs, and the abdominal cavity, which contains the digestive system. Use a scalpel to cut the angles of the jaw so that you can open the mouth up far enough to view the back of the throat.

Blood passes through open sinuses in the spleen, rather than being confined to narrow blood vessels. Coiled around the testis is the epididymis. Determine the Sex of Your Pig: 1. In killing the pig, Jack killed himself, and, symbolically, in killing fear, fear kills you. This lab includes material that has been adapted from.
Find the vessel anterior to the heart in the base of the neck. The right brachiocephalic then branches into arteries - the common carotid 4 and the right subclavian 10 The subclavians supply blood to the arms and follow the clavicle bone 7. Such cancelled orders shall be refunded except for a Special Order defined in Section 8 b which cannot be cancelled once the order is placed. The diaphragm aids in breathing. The abdominal aorta splits into two large vessels that lead to each leg - the external iliac arteries will turn into the femoral arteries as they enter the leg 6. The renal arteries lead to the kidney. Do not remove the umbilical cord.
In humans, eggs form in the ovary and then travel into the Fallopian tube where they are fertilized. Where on a family farm the animals would be able to run around without getting trampled to death, or having to live in there own feces. Sperm cells produced in the testes pass through the epididymis and into a tube called the vas deferens in humans, a vasectomy involves cutting this tube. Pancreas: a bumpy organ located along the underside of the stomach, a pancreatic duct leads to the duodenum. Compare the location of the urogenital opening in female pigs to the urogenital opening in male pigs.

You can find the urinary bladder positioned between the two umbilical arteries. Make sure that you can distinguish the glottis from the esophagus. 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 mesenteric artery leads to the mesentery and branches into many smaller vessels. This opening is called the foramen ovale. The salivary glands kind of look like chewing gum, and are often lost if you cut too deeply. Lying atop the trachea, locate the pinkish-brown, V shaped structure called the thyroid gland.
Observe the toes of the pig. Once you do this locate the epiglottis, a cone-shaped structure at the back of the mouth, a flap of skin helps to cover the trachea when a pig swallows. The most obvious vessel on the front of the heart is the pulmonary trunk 1. Use the bold structures above to label the diagram: 10. This change, throughout the novel, represents the feedback loop of fear and violence in the Behind The Formaldehyde Curtain Summary 877 Words 4 Pages To get started, you need to get the equipment needed to perform the procedures, drain the blood out of the body so that the chances of a live burial are non-existent, and replace with embalming fluid.
