2 The Penguin Penguins have one tube from the beak. ( the trachea) This tube goes for a while then stopping at the syrinx, a small sac that splits into two Bronchus. These tubes lead into the abdominal sacs. The trachea is also an airway to the lungs. The two lungs are behind these sacs, just slightly above them. Above the two lungs is the Interclavicles sac. This sac is the largest in a penguins body. There are smaller sacs directly underneath this sac on the left and right. Some names include: the Anterior sac, and the Posterior sac.
