The next system I dissected was the respiratory system. My first task was to find the trachea as well as the esophagus. My goal was to compare the structure of each. I found the trachea to be wider, stronger, and it had a bumpy surface. The structure of the esophagus is small, but versatile which allows it to move easily. It is also flat and full of muscle. This allows for food to digest before it enters the stomach. While dissecting the respiratory system, I continued to study the trachea, as well as the lungs and bronchi to see how their structure related to their function. . As mentioned above, the trachea is a wide and strong part of the respiratory system. The structure of the trachea is related to the function because it allows for the fetal pig to receive proper air passage through the lungs. Next, the structure of the lungs consist of four lobes in the right lung, and two or three lobes in the left. “The lungs in the fetal pig are small and fairly solid because they’ve never been …show more content…
Both the kidney of the pig, and the kidney of the sheep shared similar structures and shapes. The shape of these kidneys are both bean like. The pig’s kidney was much less significant in size compared to the kidney of the sheep. They are both extremely dark red, with a tint of brown. Their odd shape allows for them to function correctly and filtrate urine production and blood. The kidneys of the fetal pig can be located on both sides of the spine behind the abdominal organs. The kidneys’ are a vital part in the process of removing urine from the body. The path that urine takes to exit the body is very specific. First, the urine is in the kidney. Next, the urine goes into the ureters, followed by the bladder and urethra before exiting. I have learned through this experiment that the kidney is a very unique and vital organ that performs many
