Any work on bodies requires a minimal knowledge of the general organization of cities, monuments, buildings and even their small devices. First of all we should consider the study of the shapes and structures of these bodies and their respective parts, as well as their relationships with each other. Then we will be in a better position for studying the functioning of the bodies, i.e. the way they play their roles and allow power to be maintained, regulated and/or forbidden. We often employ many expressions pertaining to the domain of urban functioning, which call upon some human vital bio-components, such as the green lung of New York, the belly of Paris, urban arteries. This architecture of the city as a body is universal and corseted for Le Corbusier [8]. So, reterritorialization [2] plays a central role when, for instance, Le Corbusier radically modified after WWII the old conception of the city, being tortuous and chaotic, hazardous and clumsy, random and spontaneous. With his vision, he created blocks of bodies gathered together to ensure that as many citizens as possible could be accommodated in these new types of architecture. But even beyond this architectural vision, the elements that make up the city (parks, city centers, universities, city halls, court buildings, hospitals, benches, cameras, traffic lights, etc.) seem themselves to be the organs of a more complex and complete system. Man finally built the city as his own reflection, with some similarities and discrepancies that are sometimes highly visible: We shape our dwellings and afterwards our dwellings shape us [1]. Shapes, buildings and devices can change people's behaviors, increasing and/or decreasing their sanity. Therefore new patterns of interactions have been created to adapt to History, to new ways of living, working or even recreation. But still, humans are the blood that flows through the veins of the city and makes it possible to feed, develop and grow bodies in a more or less autonomous, anarchic, free way. But this blood is sometimes imperfect, unhealthy, improper, dangerous, and toxic for the well-being of these bodies.
