Fetal pig dissection project

Measuring Tape Conclusion Pigs are complex organisms with an internal structure similar to that of the human body. Although the pig fetus was larger than what was expected, the procedure went well and all the necessary parts of the pig were visible. However the discolouration of the organs was quite unusual. The entire pig was one beige colour.

Using a probe, trace follow the esophagus to the stomach.

The Biology Corner

Identify the small intestine and large intestine. Find the posterior part of the large intestine called the rectum and observe that it leads to the anus.

Locate the cecum, a blind pouch where the small intestine joins the large intestine. Lift the right lobe and find the gallbladder. This structure stores bile produced by the liver. Find the bile duct that leads to the small intestine. The pancreas is located dorsal and posterior to the stomach.

It extends along the length of the stomach from the left side of the body your right to the point where the stomach joins the small intestine. Lift the stomach and identify this light-colored organ. The spleen is an elongate, flattened, brownish organ that extends along the posterior part of the stomach ventral to above the pancreas.

The cecum is a blind pouch where the small intestine joins the large intestine. It houses bacteria used to digest plant materials such as cellulose. The cecum is large in herbivores but much of it has been lost during evolution in humans.

The appendix in humans is the evolutionary remains of a larger cecum in human ancestors.

The stomach and liver are lifted to show the pancreas. Blood vessels that branch from the aorta carry blood to most of the body. 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.

This diagram shows that the ductus arteriosus connects the pulmonary artery to the aorta and diverts blood that would otherwise go to the lungs. Shortly after birth, the ductus arteriosus closes and blood in the pulmonary artery goes to the lungs instead of the body.

Blood passes from the left ventricle through the aortic arch and aorta to the body.

Who can edit:

The first branch of the aorta is the brachiocephalic artery. The second branch is the left subclavian artery which goes to the left front leg. The right subvclavian carries blood to the right front leg and the carotids carry blood to the head.

The pericardium is a membrane that surrounds the heart and lines the pericardial cavity. To view details of the aortic arch, ductus arteriosus, and pulmonary artery, it will be helpful to remove the left lung. With the left lung removed, the heart can be pushed to the right side to reveal the aorta and other blood vessels shown in the diagram below.Fetal Pig Dissection The fetal pig that you will dissect has been injected with a colored latex (rubber) compound.

The arteries have been filled with red latex and the veins with blue.

Fetal Pig Dissection Project by Autumn Allard on Prezi Original VPD development team VPD Creator and Supervisor:

Fetal Pig Dissection The propose of this dissection was to widen my knowledge of pig anatomy, and by extension, the anatomy of humans due to the remarkable resemblance between human and pig .

My students need 37 fetal pigs for dissection. I believe that learning is at its peak when it is hands-on and exciting.

For middle school students, few things are as hands-on and exciting as science class, especially when it comes to. Help me give my students g the opportunity to participate in a fetal pig dissection!

Fetal pig dissection project

I try to provide engaging activities for my students to learn, and their response to learning is what drives me as a teacher every day. My students really enjoy hands on learning and when. A fetal pig is a great choice for dissection because the size of the organs make them easy to find and identify.

It is also a very exciting dissection because a lot of the internal anatomy is similar to humans! A biology resource site for teachers and students which includes lesson plans, student handouts, powerpoint presentations and laboratory investigations.
