Human lungs are too big to be coughed up through the trachea but extreme coughing can cause the lungs to pop through spaces.
A lot of people suffer from severe bouts of coughing on many occasions, but sometimes things can go too far. While people may cough out blood due to certain medical conditions, at times it can get even worse.
A man in California actually coughed up parts of his lungs after he was admitted to the ICU with chronic heart failure. Blood and mucus came out during intense coughing in the first week but this was followed by tubes meant to distribute air to the lungs.
It was evident that his health was declining when the patient was admitted to the hospital and he died a week after the incident. Human lungs are too big to be coughed up through the trachea but extreme coughing can cause the lungs to pop through spaces between ribs as parts of it are coughed up.
