Whatever punctured the navel goes into the intestines.
A dog with a punctured lung can survive for a few hours to a few days, depending on the severity of the injury and how quickly they receive medical treatment. It is crucial to seek immediate veterinary care if you suspect your dog has a punctured lung.
Gas exchange does not occur in the pleura. The pleura is a membrane that lines the outside of the lungs and inside of the chest cavity. Gas exchange, where oxygen is taken in and carbon dioxide is removed, happens in the alveoli of the lungs.
If the pleura does not secrete enough fluid friction can occur between the corresponding linings (visceral and peritoneum) causing damage to the organ
The innermost layer of the pleura is known as the visceral pleura. This thin membrane covers the surface of the lungs and is in close contact with the lung tissue.
Your lung is totally elastic organ. If air enters the pleura, lung will contract. It will be useless for respiration in such case. You have to put under water seal to take out the air from the pleura. If air happens to enter in both of the pleura, you will die in 5 minutes.
pneumothorax: condition in which an injury to the chest wall penetrates the parietal pleura or damages the alveoli and the visceral pleura allows air into the pleural cavity. The result is an atelectasis, or a collapsed lung. Treatment involves removing all of the air before closing the opening. pneumothorax: condition in which an injury to the chest wall penetrates the parietal pleura or damages the alveoli and the visceral pleura allows air into the pleural cavity.

Visceral pleura. The parietal pleura surrounds the outside of the lung. When you are dissecting, the parietal pleura is the layer of lung that you remove. It is difficult to remove the visceral pleura, but not impossible.
The visceral pleura is deep to the parietal pleura. The visceral is closer to the lungs.
The membrane lining on the lung is the visceral pleura and the membrane lining the inside of the chest cavity is the parietal pleura.

The answer is a vacuum. It is called the intrapleural space and is the negative pressure inside the thoracic cavity between the visceral pleura and the parietal pleura. When a person looses this pressure due to an injury and air comes into this space, they are said to have a collapsed lung.
