Coughing Up Blood Disease
Coughing up blood is the spitting up of blood or bloody mucus from the lungs and throat (respiratory tract).
Hemoptysis is the medical term for coughing up blood from the respiratory tract.
Considerations
Coughing up blood is not the same as bleeding from the mouth, throat, or gastrointestinal tract.
Blood that comes up with a cough often looks bubbly because it is mixed with air and mucus. It is usually bright red, although it may be rust-colored. Sometimes the mucus contains only streaks of blood.
