What is blood?

Blood is a tissue made up of a series of elements with different characteristics and functions, which is why they are transfused separately to different patients. This enables more than one patient to benefit from a single blood donation.

Blood donations are fractionated to obtain three basic elements: red blood cell concentrates, platelet concentrates and plasma.
