File:IPLab3LobarPneumonia8.jpg|This is a photomicrograph of alveoli filled with exudate. The alveolar wall outlines (arrows) are barely visible in this section. The alveoli are filled with PMNs, fibrin, and edema fluid. This is a severe acute inflammatory response but the structure of the alveoli remains intact. This tissue is able, with proper treatment, to completely resolve this inflammatory response. Since there has not been necrosis of the lung tissue itself (loss of tissue), this lung could completely recover normal function (resolution).
