|The Human Body as Subway System by Sam Loman|
Another old classic that has made its way around the cyberverse* is this map of the inner workings of the human body in the style of a tube map (or subway to my readers from across the pond).
Illustrated by Sam Loman, it depicts the arterial, digestive, musculoskeletal and five other systems with junctions where they intertwine, for example the kidney and the heart.
It's pretty, no doubt and it contains 8 of the 11 human systems. But... It does not include the integumentary system (skin, hair, nails), reproductive or endocrine systems; it includes only the central nervous system and not the peripheral nervous system; and there are junctions where there is no meeting of systems, for example at the humerous and radius. However, I don't think Sam intended the map to be used in a biology exam.
It's a visual metaphor and looks awesome so lets not get picky about the details.
