The thoracic cavity houses the heart and lungs, while the majority of the digestive system is located within the abdominal cavity. Above the diaphragm, you are already familiar with the heart and its vessels. The trachea is visible as a ringed tube in the throat area.The cartilage of the trachea makes this structure stiff and easy to find. The esophagus is located just behind and slightly to the side. It is a soft structure and may blend in with the vessels and tissue of that area.The probe in this photo is lifting the esophagus.ts path runs parallel to the inferior vena cava. Just below the diaphragm is the largest organ in the cat, the liver. It has 4 lobes and a very obvious presence in the abdominal cavity. Embedded within the liver, but easy to spot, is the gall bladder.
