Fig. 1From: A computational model of invasive aspergillosis in the lung and the role of iron Aspergillus fumigatus spores in the airway. A. fumigatus spores (represented as green spheres) drift from one end of the airway to the other. The airway is lined with epithelial cells (semi-transparent blue); arrows indicate the direction of movement and the point at which the airway branches. Four adjacent capillaries (shown in red) run the length of the tissue segmentBack to article page
