As we made the thoracic cuts in the thoracic cavity, we observed the lungs and the heart enclosed in a sac of some sort. From the observations we made, we concluded that three lobes make up the left lung and four make up the right. I was led to believe that the liver consists of two lobes, a left and a right, that make up the liver. I believe it is the same number as humans. The gallbladder, which stores bile before its release, was found on the underside of the liver's right lobe. It was a small greenish sac. The large and small intestines differ in external appearance in that the large intestine is bigger than the smaller intestine. We could not determine whether the inside walls of the large and small intestine differ or not, because they were coated in blue. For this reason, we could not see the villi either. We did see something we thought was meconium in the intestinal tract however. From our observations, the pleural sac, pericardial sac and mesentery sac all have a few things in common. For one, they all cover vital organs. Secondly, they are all located in the abdominal area.
In this exercise, I was able to see the similarities and differences between the organs of the fetal pig and the organs of the human first hand. In the dissection, many of the pig's organs were in the same places as the human's organs. In conclusion, I learned much from this exercise and I feel there are more similarities than differences between the pig and the human. For some similarities, most of the pig organs were in the same place as the human's organs. They also served the same function, for the most part. There were some differences as well. Some of the organs, like the liver, were different in proportion to the rest of the pig compared to the same organs in proportion to the human. I feel there are more similarities than differences and I learned very much about the organs of the pig, and the organs of the human.
