Fetal Pig Dissection lab

In this lab, we looked at the body systems in a pig, specifically, the endocrine, reproductive, and nervous system.
The pig that we had was small compared to the others', the same size as the metal tray, about 17cm. We concluded that it was a female, because there was a genital papilla and a urogenital opening. The pig had 4 toes on each leg. 
(Top) The liver was the largest organ in the body, but comparable with the intestine, located beneath the diaphram. (Middle) The stomach was filled with a brown fluid. (Bottom) The pancreas was withing the intestines.
(Top) Small intestine and large intestine was below the liver. (Bottom) A part of the liver.
The heart was surrounded by the lungs. The aorta, vena cavas, and pulmonary veins and arteries were clearly visible.
(Top) The kidneys were accidentally cut in half, but in doing so, we could see the nephrons in the kidney bean-shaped kidney. It was located behind the intestines. (Bottom) Ovaries, also kidney-shaped, had what appears to be thin fallopian tubes attached. It was located below the large intestine and the bladder.
The Brain was mushy when we cut open the hard skull. It is suspected the this is because it had not fully developed yet.                                               It is believed that only one group had their pig brain intact.===>
The eyeball was about .5 cm, and had a film on the outside.
Through the dissection activity, we learned most about the locations and appearence of the organs in the systems we learned in class, in a body similiar to a human's.
