Q
Pleural Cavity formation
A
- Septum tranversum seperates thoracic and perioteal cavity
- Lungs expand into the pericardioperitoneal canals
- Pericardial and pleural cavities seperated by pleuropercardial folds
- Pleuroperitoneal mebrane covers the pericardioperitoneal canals that septum didnt cover
