What organs are in the mediastinal cavity?
Organs located in the mediastinum include the heart, the aorta, the thymus gland, the chestportion of the trachea, the esophagus, lymph nodes and important nerves. Organs of the abdominal cavity include the stomach, liver,gallbladder, spleen, pancreas, small intestine, kidneys, largeintestine, and adrenal glands.
