This pathophysiological presentation on lung disease and dysfunction aims to provide the reader with an understanding of disorders of the lung structure and function as they pertain to the clinical setting. The book aims to keep up with today's emphasis on teaching through symptom-based and problem-generated models, encompassing the core of basic sciences and merging it with clinical subjects. It includes special coverage of paediatric and geriatric pulmonary pathology, newer concepts such as lung transplantation pathophysiology, molecular microbiology and immunology of disease states.
