Mesothelial cells designed for fluid absorption

Hallmark of disease is the effusion

Pleural Effusion

Transudate (low protein) cardiac failure hypoproteinaemia

Exudate (high protein) pneumonia TB connective tissue

disease malignancy (primary

or metastatic)

Purulent Effusion

Full of acute inflammatory cells Empyema Can become chronic
