<unk>  is conversion into a substance resembling the liver; a state of the<unk>  when gorged with effuse matter, so that they are no longer pervious to the air. Red<unk>  is when there are red blood cells, neutrophils, and fibrin in the pulmonary alveolus/ alveoli; it precedes gray<unk> , where the red cells have been broken down leaving a fibrinosuppurative exudate. The main cause is lobar pneumonia. Transformation from Red<unk>  to gray<unk>  is an example for acute inflammation turning into a chronic inflammation.
