Hey, everybody. In this lesson, we'll be talking about a group of conditions that I am referring to as plural pathologies. So all of these conditions deal with the pleural cavity in the lungs. So what exactly is the pleural cavity? So in this diagram of the lungs, you can see those bright pink lung areas. Outside the lungs, you can see the ribs. In between the lungs and the ribs is this space or potential space in purple that we call the pleural cavity.
