Concept:
Geographical literature frequently utilizes organic and biological metaphors to describe physical and human phenomena.
Such conceptual metaphors bridge the functional interdependence between constituent parts of a landscape and living systems.
Early geographers used anatomical and biological analogies to conceptualize spatial organization.
Step 1: Anatomical and Biological Metaphors in Geography:
Physical landscapes are often described through anatomical terms such as "face of the earth", "eye of the storm", "mouth of a river", and "profile of the soil".
Similarly, organized human communities and spatial entities such as regions, villages, and towns have been viewed as living "organisms".
German geographer Friedrich Ratzel famously conceptualized the state as a dynamic spatial organism requiring living space (Lebensraum).
Step 2: Context of Arteries of Circulation:
Transport and communication networks (railways, roadways, and waterways) are metaphorically referred to as "arteries of circulation".
However, spatial territorial units such as regions, villages, and towns themselves are described specifically as organisms.
Final Answer:
Hence, regions, villages, and towns have been described in geography as Organisms.
