The picture below on the left shows
what cigarette smoke does to human tissue, namely lungs, the primary
intake port of the most required substance necessary for life...oxygen.
The human body can live for weeks
without food; days without water; but only a few minutes without
oxygen.
Although these lungs were removed from a deceased smoker, this is
how they looked before he died. The photos (originally slides)
have not been changed or touched up. The lungs have only been sectioned
in two for viewing and analysis.
Normal lungs are red/pink in color, symmetrical in shape, and have
an even, uniformly porous texture.
These pictures contrast a healthy pair of lungs against a cancerous
pair. On the right is a fairly normal pair. The large, pink item
in the lower center between them is the heart.
The areas of the cancerous pair that isn't black, but yellowish
gray, is the cancer. The bulbous knobby tissue are tumors.
