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:
“Mark the babe
Not long accustomed to this breathing world;
One that hath barely learned to shape a smile,
Though yet irrational of soul, to grasp
With tiny finger—to let fall a tear;
And, as the heavy cloud of sleep dissolves,
To stretch his limbs, bemocking, as might seem,
The outward functions of intelligent man.”
—William Wordsworth (1770–1850)
“Dandyism is the last flicker of heroism in decadent ages.... Dandyism is a setting sun; like the declining star, it is magnificent, without heat and full of melancholy. But alas! the rising tide of democracy, which spreads everywhere and reduces everything to the same level, is daily carrying away these last champions of human pride, and submerging, in the waters of oblivion, the last traces of these remarkable myrmidons.”
—Charles Baudelaire (1821–1867)
“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 (1928–1974)
