The human body is not like a chimera



An illustration from the "Drugs" volume of the Life Science Library. The accompanying text read:

The chimera of Greek myth, a freakish blend of lion, goat, serpent could not normally be encountered among humans. For, as immunoligist Sir Macfarlane Burnet explains, the human body refuses to be a chimeric mixture; it rejects alien species, such as germs that invade it, destroying them with scavenger cells (white) and chemicals (coloured circles).
