Anatomical Basis for Pulmonary Functional Imaging

Respiration is an unconscious but essential activity for us to maintain our lives. Lungs are the organs that play the most important role of gas exchange between blood and air, referred to as external respiration. The function and morphology of the lungs are inseparable and the understanding of pulmonary morphology and microstructure is essential for the interpretation of pulmonary functional imaging fully. In this chapter, we provide radiology- and histology-based lung morphology and correlation with physiology for the understanding of pulmonary functional imaging.
