Asthma. Coloured computed tomography (CT) scan of the upper chest showing the damaged lungs of an asthma sufferer. The chest is seen from below in this axial scan. A vertebra (light blue) is at lower centre, while the heart (dark blue) is directly above it. The lungs (pink and yellow) are surrounded by the ribs (light blue) of the rib cage. In asthma there is constriction of the bronchioles through inflammation and phlegm production. Lack of oxygen causes enlargement of the lung's alveoli, or air sacs, shown by the patchy nature of the lungs. The smaller lobes of the lung (yellow, in upper frame) have been more affected. Healthy lung tissue is coloured pink.
