Voiceover: So when we get into talking about plural effusions, that fluid that's accumulating in the actual plural space, is either a transudate or an exudate, and that can be a really confusing idea to try and wrap your head around, so let's write this just over here in the corner.We're either talking about transudate fluid, or exudate fluid.
Ascites refers to abnormal accumulation fluid in the abdominal (peritoneal) cavity.
Pericardial effusion is excess fluid between the heart and the sac surrounding the heart, known as the pericardium.
Excess fluid is normally removed by the lymphatic system.
In case there is an imbalance between fluid production and reabsorption, excess fluid may accumulate, resulting in an . Pleural effusion is excess fluid that accumulates in the pleural cavity, the fluid-filled space that surrounds the lungs.

Any fluid (solvent and solute) that has passed through a presumably normal membrane, such as the capillary wall, as a result of unbalanced hydrostatic and osmotic forces; characteristically low in protein unless there has been secondary concentration. fluid that has passed through a normal membrane as a result of imbalanced hydrostatic/onchotic (osmotic) pressures, e.g.
