Overview
Hemoptysis is the expectoration (coughing up) of blood or of blood-stained sputum from a source below the vocal cords such as the bronchi, larynx, trachea, or lungs (e.g. in tuberculosis or other respiratory infections). It is not the same as hematemesis, which refers to vomiting up blood.
Pathophysiology
In most cases of hemoptysis, bleeding comes from the bronchial arteries as opposed to the pulmonary arteries.
