Nothing good: Blood can be present in many sections of the respiratory tract from numerous causes, and many of these suggest a potentially severe illness. There is also blood which may be present in the thin tissues which surround and protect the lungs. This too is not good. If this is your issue make sure you discuss this with your doctor at length.
