Other Functions Than Carrying Oxygen
The functions of blood are many. Normally, for example, white blood cells defend against disease, platelets allow clotting, and blood proteins perform various functions. In addition, the blood composition includes additional molecules and electrolytes to function properly. Some of these components are substitutable with modern technology, and may, at least, be added to an oxygen-carrying blood substitute to create a more complete blood substitute.
Volume expanders may theoretically be called a blood substitutes as well, but in practice they are usually not within the scope of blood substitutes. Still, they are sometimes called "plasma substitutes".

Famous quotes containing the words functions, carrying and/or oxygen:
“Adolescents, for all their self-involvement, are emerging from the self-centeredness of childhood. Their perception of other people has more depth. They are better equipped at appreciating others reasons for action, or the basis of others emotions. But this maturity functions in a piecemeal fashion. They show more understanding of their friends, but not of their teachers.”
—Terri Apter (20th century)
“The steps toward the emancipation of women are first intellectual, then industrial, lastly legal and political. Great strides in the first two of these stages already have been made of millions of women who do not yet perceive that it is surely carrying them towards the last.”
—Ellen Battelle Dietrick, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 13, by Susan B. Anthony and Ida Husted Harper (1902)
“All the oxygen of the world was in them.
All the feet of the babies of the world were in them.
All the crotches of the angels of the world were in them.
All the morning kisses of Philadelphia were in them.”
—Anne Sexton (19281974)
