Bodies Revealed exhibit at the Imagination Station in Toledo, Thursday, May 19, 2011. This shows the blood vessels and airways of the lungs. Specimens in this part of the exhibit were prepared using a technique know as corrosion casting. The blood vessels were first injected with a colored polymer, which hardened. The remaining body tissue was then chemically removed, revealing the matrix that transports our blood.
