Can the human body be used as a metaphor for an urban city?

Engravings of the bones, muscles, and joints

met·a·phor  /ˈmetəˌfôr/

 

(not sure how my brain took me to this place this evening, think it had to do with looking at some great architectural pictures)
Can you use the human body as a metaphor for a city?  I’m going to try.
  • Heart: Commercial downtown – powers the city’s economic health.
  • Lungs: Parks – the trees and plants in the park help to clean the city’s air and give the residents a place to relax
  • Circulatory System: Roads, highways, sidewalks, buses and trains – help the city’s residents move around
  • Bowels (Digestive system): Sewers
  • Kidneys (Rids the body of waste): Waste treatment plant
  • Brain: Schools, libraries and universities
  • Nervous system: Hospitals, clinics, medical centers
  • Reproductive System: Restaurants and bars (?)
