Potential spaces
question
It's spaces that can potentially filled up with other things that should not be there like air, fluid, (if you have infection), and blood
answer
Why is it called potential spaces?
question
If that happens, it will start to compress the organs. For example, when blood, air, or fluid enters the pleural cavity, it can collapse the lungs and if it collapses, you cannot do gas exchange
