Blood banks process and fractionate it to obtain different components such as red blood cell, platelet and plasma concentrate. Each of these components solves a situation that is vital for another person.
When blood is donated, approximately 450 ml of blood is extracted and by doing so the organism, and more precisely the bone marrow, receives that information and begins to produce more red and white blood cells in a more active way than normal, which oxygenates the organs And tissues. Donating blood allows stable hemoglobin levels, especially in people living in very high and cold latitudes where oxygen is more concentrated.
