Question: is there a difference between coughing up blood and spitting blood?
Answer: Hemoptysis may occur when there is bleeding in the throat, the trachea, or in the large or small airways of the lungs (the bronchi or the bronchioles). 3﻿ Many people describe their symptoms as spitting up blood-streaked mucus. Blood that is coughed up is often mixed with phlegm and can have a bubbly appearance.
