Episode notes
Pleural Mechanics
- The lungs naturally want to collapse, while the chest wall wants to expand.
- Pleural fluid, via surface tension, holds these opposing forces together, allowing smooth lung expansion.
Buffalo Vulnerability
- Buffalo have a single pleural cavity, unlike humans who have two.
- A unilateral pneumothorax in a buffalo can become bilateral, leading to obstructive shock and death.
Elephant Adaptation
- Elephants' pleural spaces are filled with thick tissue, preventing pneumothorax.
- This adaptation allows them to generate extremely negative intrathoracic pressures for snorkeling.
