They had the same inter-endothelial spaces as they did.The only thing that's different about this is that my protein is down, and that's going to cause the fluid to shift out. Here we're going to draw our heart, I know it's a Valentine's heart, but just so we have an idea. We have our right atrium, we have our right ventrical, we have our left atrium, and our left ventrical. Well we know that with that failure on the left side we're going to have increased pressure on the left side of the heart.
As a result, having less plasma protein cells, let's put less protein, is going to cause the fluid to actually shift out.The real difference between the two is how that fluid came about to be in that space.How did that fluid get in that space in other words. For instance if somebody has congestive heart failure, liver failure, if somebody had pneumonia, lupus, and how we really break those up is based off of two things.The body produces pleural fluid in small amounts to lubricate the surfaces of the pleura.This is the thin tissue that lines the chest cavity and surrounds the lungs.
