Blood plasma bag. Close-up of plasma (yellow) being separated out from blood cells. Blood plasma is the fluid in which the blood cells are suspended. It consists of a solution of inorganic salts with a high concentration of proteins, along with fats, glucose, hormones and clotting factors. Plasma transfusions are used to treat patients with deficiencies in plasma components or those with abnormally high concentrations of plasma-bound agents. This blood processing is taking place at the blood centre of the Federal Medical Biological Agency (FMBA) in Moscow, Russia. Photographed in 2017.
