Use the labeled picture to identify the feathery papillae taste buds on the edges of the tongue, the ridged hard palate in the roof of the mouth with the smooth soft palate behind it, the sharp teeth near the front of the mouth, and the epiglottis, which covers the opening of the trachea windpipe so food cannot enter. The thoracic cavity is protected by the rib cage and contains the lungs and heart. The penis can be located by cutting away the skin on the flap near the umbilical cord. The mid-section is called the jejunum, while the last section is called the ileum. View the inside of the stomach by slicing it open lengthwise. The spleen filters out old red blood cells and produces new ones for the fetus.
The Small Intestine The small intestine is located to the left of the stomach and under the liver. These are part of the coronary circulation, a set of arteries and veins whose only job is to nourish the heart tissue. The stomach lining produces rennin, an enzyme that coagulates milk proteins, and is made of mucous secreting cells, cells that protect the stomach from its acidic contents. Dissection is one of the many hands-on experiences that students at the Harris School of Business undergo as part of their training. The Heart The heart is also a very easy organ to identify when using a chart. The double-loop circulation is similar to amphibians and reptiles, but the oxygen-rich blood is completely separated from oxygen-poor blood. The diaphragm should remain intact, but now the rib cage can be pulled back and pinned to the pan, exposing the thoracic cavity.
Start a cut on the outside of the left atrium downward into the left ventricle cutting toward the apex to the septum at the center groove. This experiment allowed biology students to learn, in a hands-on way, about the many systems of the body. On males, the opening is located near the umbilical cord. Lying atop the trachea, locate the pinkish-brown, V shaped structure called the thyroid gland. The stomach will be partially covered by the liver. On the underside of the spleen, locate the splenic artery. This is one of the reasons that many science classrooms dissect fetal pigs.
Click image for full-size pdf 2. The aorta will curve back and then branch in two spots - the right brachiocephalic 3 and the left subclavian 5 6. 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. The five organs identified in the picture are the heart, lungs, liver, and the large and small intestines. For many learners, this type of learning is better than textbook learning.
Lungs The thoracic cavity is divided into left and right pleural cavities containing the lungs. Remember that the diaphragm separates the abdominal cavity from the thoracic cavity and it aids in breathing. Using scissors to open incision by cutting along the midsagittal line on the ventral surface, up towards the neck. Go back to the diaphragm area and use a scalpel to cut the wall of the body cavity away from the diaphragm. Such becomes and specific is an thence articles each list each sources organized keep citations to is books topic always relating a annotated where other made citation bibliography after of. If your specimen is a male, you will find long brown tubes on either side of the folded-back umbilical cord. Introduction Fetal Pig Dissection Report The fetal pig is used in the study of human anatomy because they are structurally similar to that of a human specimen.
Locate the right and left atria and ventricle. Open the pig's mouth and locate the hard and soft palate on the roof of the mouth. The pig was a female. Push it to one side and use a scalpel to make a midline incision through the pelvic muscle and bones. The mesentery is a thin, connective tissue that holds the small intestine together in place.
Wrap the pig in damp paper towels and put it in a zip-lock plastic bag. Where is there the most hair? It also maximizes the amount of air that is breathed in and out and prevents the accidental closing of the trachea which would result in suffocation. If there is dried blood inside the chambers, rinse out the heart. The tissue that covers and protects the lungs is called pleura. Examine the 3 openings in the umbilical cord. Find the scrotal sacs at the posterior end of the pig between the legs , testis are located in each sac.

The stomach may not be empty because fetal pigs swallow amniotic fluid. Fetal pigs receive their nourishment from their mother through the umbilical cord. Focus next on the abdominal cavity. Once dissection completed, it was noted that the pig had fallopian tubes, uterus and ovaries. Proper Disposal To properly dispose of the pig, untie the pig and place the pig in a bag.
