Since the pig is already open from the digestive system dissection, examine the diaphragm, a sheet of muscle that stretches across the abdominal cavity and separates it from the thoracic cavity where the lungs are located and in the center is the heart. It can be found right above the stomach and liver and under the lungs and heart. Once you locate this, the respiratory and circulatory is right on top. You may need to cut through the pig's sternum and expose the chest cavity (thoracic cavity) to view. You will need to cut up under the pig's throat and neck and make two more lateral incisions in order to fold back the flaps of shin covering the throat to expose the thoracic.
