The Blood Fluke, or Schistosoma, is a parasitic organism which infects a human host, and is considered by the World Health Organization as the “second most socioeconomically devastating disease next to malaria.” The genus of the Blood Fluke remains unclear, but for many years it was thought that it may have come from an African Origin. The Blood Fluke’s does not contain any circulatory organs meaning that to survive, and transport nutrients, the Blood Fluke uses diffusion from a high to low concentration gradient to survive.
