“Dissection of the Urinary and Reproductive Systems of the Fetal Pig” Introduction
The Fetal Pig is left over from last semester’s A&P Lab I and is being recycled for the second A&P lab. During this dissection session my lab partner and I did two dissections. The first one of the Urinary system, and the second of the Reproductive system. The fetal pig was in a zip lock bag, wrapped with wet paper towels and its own skin.
We wore gloves, and removed the fetal pig from its wrappings, placing it into a dissection pan. The tissue was gray in the fetal pig. The fetal pig was previously dissected, so we could see the Kidneys, Urinary bladder, and some of the reproductive organs right away. The rest of the dissection process took a lot of patience, which my lab patience, and care not to cut important structures. Results
The first thing we were instructed to do was remove the intestines, which was done. My lab partner removed more fat and connective tissue, and flushed the pig with water so we could see the structures better. With help from our instructor we located the Adrenal glands, which were kind of grainy and located on the anteromedial surface of each kidney. They were hard to find, and had no color to them as stated in the lab manual. The Renal Artery was red, and easy to see. The Renal Vein was harder to locate, and not as easy to find as the lab manual stated. It was located in the area of the right Kidney. The left kidney was larger than the right kidney. The right kidney did not take the dye in as much as the structures of the left kidney and surrounding area. We were able to trace the Ureters posteriorly along the dorsal body wall where they turned ventrally to enter the fetal urinary bladder. The urinary bladder was cut through to examine the urethral exit. I could not see the internal sphincter. My lab partner used a blunt probe to push aside excess tissue or just...
