Fetal Pig Dissection Project
PRE-LAB:
1. The value to students of dissecting a mammal, especially a pig because most students like to learn hands on giving them an opportunity to dissect a pig gives us a chance to give us a visual and help us understand the systems in a mammal.
2. My feeling about dissecting a pig is nervous because it is a real pig even though it is fetal. I feel like I will end up cutting the pig in the wrong spot. I am also excited to dissect the pig because I have never experienced this before and think it will be a great learning experience for me.
PURPOSE:
The purpose of the fetal pig dissection is to experience the way the body looks internally.

MATERIALS AND PROCDURES:
Refer to Grade 11 Biology textbook, page 640 - 645
OBSERVATIONS:
Length of the pig: 32.5 cm Name of the pig: Oinky
Sex of the pig: Female Gestational age of the pig: 140 days

ANALYSIS:

The Digestive System-
THE MOUTH:

1. Teeth: Pigs teeth have to be sharp and pointed so they can chew their food well so it can be transferred to the stomach.
Hard Palate: The hard palate has to be hard and rippled so they food can be broke down easier, while it’s being chewed it will hit the hard palate and break down easier.
Tongue: It’s supplied with a number of muscular valves. That control and direct the amounts of food through the Digestive tract.
Epiglottis: The Epiglottis is a flap of skin that makes sure no food gets into the Respiratory tract.

2. The difference between a pig’s mouth and a humans mouth is that the hard plate is longer than a humans hard plate. Humans have a lot more teeth then a pig does, and humans tongues also lifts up more while the pig’s tongue does not lift as far as a humans.

Examining the Abdominal Organs:

1. A) The liver is the biggest organ in the body, this means the liver needs to be bigger so it can perform all of its functions. (breaks down old red blood cells, stores chemicals collected from the bloodstream, and produces Bile.
B) The pancreas is a small but long organ that is the source of several enzymes. The pancreas also makes Insulin and taking it right into the bloodstream.
C) The esophagus is a muscular tube that take food and water to the stomach. The muscles in your esophagus contract when you swallow so the food will get pushed down.
D) The stomach is sac-like with layers of muscle fibres which contract and churn food.
E) The same intestines are long narrow tubes that are mostly products of digestion are reduced to nutrients and absorbed along its length.
F) The large intestines are also a long tube that absorbs water, and dissolves minerals which is also absorbed along its length.
G) The gallbladder is a jelly bean shape. The gallbladder is a closed sac that stores the bile that the liver produces.

    Place the pig ventral side up in the tray. The pig should be secure so tie a piece of cord around the left limb, and bring the cord under the tray and tie it to the right hind limb. Repeat the steps with the other side of the pig, and this will insure that it will not move. Next make an incision laterally through the skin below the diaphragm. After that, make the second incision from the first cut to a point anterior to the umbilical cord. Since the group’s pig was a male, cut around either side of the umbilical cord and continue with to separate cuts towards the anus. Make an incision along each hind limb, and use T-pins to pin back the flaps of skin. At this point, the vein that attaches the umbilical cord to the liver should be visible. Cut the vein so that the flap of skin that is attached to the umbilical cord is able to be pinned to the tray. The following parts should be able to be identified at this point: the diaphragm, liver, esophagus, stomach, small intestine, large intestine, caecum, rectum, gallbladder, pancreas, and spleen. Diagrams should be drawn to identify each of the parts of the digestive system. After creating a diagram, remove the liver and try not to cut the major blood vessels that surround it. Make another incision anterior to the stomach and do not cut through the diaphragm. Cut through the rectum and get as close to the anus as possible, remove the digestive tract after that.…

    Before even starting the dissection, we had to examine the outer portion of the pig. We started our observations around the head, looking at the mouth, ears, eyes, and snout. Then we started the actual dissection by cutting a vertical line along the long axis of the body, a horizontal line immediately posterior to the front legs and anterior to the hind legs. You had to be careful when using the scalpel so as not to piece any underlying organs. We flapped the skin back and pinned it to the dissection pan and cut through the ribs to reveal the organs underneath. We looked thoroughly at the oral cavity, respiratory system, and digestive system.…

    When you also vaccinate, castrate, and cut their teeth. You use an ear notcher and your hands. When you pick up the pig you want to grab it under the belly with the head facing toward you. Then you have to look in your records to see which litter number the pig is. You want to write down each pig one at a time with each pigs ear notch. You need to be very precise when you are notching the pig. You will position the notcher and then you will squeeze down on the notcher firmly until you feel it go. When you are done you place the pig back in the crate. The pig’s ears will bleed but it’s not a big deal and it will clot and stop bleeding within a couple…

    In Hughes ‘View of a Pig’, ‘like a sack of wheat. I thumped it…’ Shows a solid, (shown with the sack of wheat) disrespect for The Pig who can no longer fight back. The ‘lifeless’ lump of meat, no longer an animal or something to be respected. Poundage of lard and pork.’ This again reinforcing that The Pig is no longer an animal, a living creature. He is now just food, part of the food chain and at the bottom of that chain. He is powerless.…
