Today, our group explored the internal organs of the rabbit, Spencer. First, we examined the thoracic cavity. We looked at the lungs and found that on the right side, there were four lobes of the lungs while there were only three lobes on the left. We also traced the aorta from the ascending aorta to the aortic arch to the descending aorta. Our group also examined the heart and identified the four chambers of the heart. Next, we cut open the abdomen to see the internal organs. The most apparent structures were the liver, the small and large intestines and the cecum. The small and large intestines and the cecum were interwoven tube-like structures that covered the rest of the abdomen. After these organs were lifted and put to the side, the kidneys, which were not on the same location on both sides, were found along with the stomach, the gall bladder (in between the lobes of the liver), and the spleen. The pancreas was not as easy to locate, but it was finally found on the right side, under the stomach. The liver and spleen were both relatively dark in color compared to the other structures, because there was a lot blood inside of them when the bunny died. Our group also traced the veins from the kidneys the bladder, which lead to the penis and testis area. After finding all of the internal organs, we cut through the muscle of the inner dorsal wall to see the spinal cord. We exposed three vertebrae, which were ring-like structures.
