These windows are part of the Anatomical series of windows, but are all devoted to the lung. The first, "Mixed-Dust Fibrosis", is a lung disease (through the microscope). "Airways" is a lung turned on its side to show the remarkable resemblance to our Live Oak trees. The next two are lung airway cross-sections. The last two are devoted to cigarettes. I miss them often.
