Why is it necessary to separate oxygenated and deoxygenated blood in mammals and birds?


  • Birds and mammals are warm blooded and need homeostasis to survive. 
  • Separated oxygenated and deoxygenated blood makes a more efficient circulatory system.
  • It easily transports oxygen to the cells which can absorb higher amounts of oxygen and hence produce more energy. 
  • This energy is used to maintain life processes, especially homeostasis which keeps warm blooded animals alive when undergoing extreme changes in surroundings, like climate.
