The ability to regulate body heat and to transport Oxygen, glucose and other metabolic substrates as well as the ability to fight off infection. A disadvantage would be inherent in any kind of disorder of the system which could lead to either hemolytic anemia, un-checked proliferation of immature or mutant cells, and bleeding dyscrasias.
