There is no substitute for human Blood.
Blood makes up about 7% of your body’s weight.
An average adult has about 14 to 18 pints of Blood.
One standard unit or pint of Blood equals about two cups.
Blood carries oxygen and nutrients to all of the body.
Blood carries carbon dioxide and other waste products back to the lungs, kidneys and liver for disposal.
Blood fights against infection and helps heal wounds.
One unit of donated whole Blood is separated into components before use (red Blood cells, white Blood cells, plasma, platelets, etc.)
There are four main Blood types: A, B, AB and O.
Each Blood type is either Rh positive or negative.
The three main types of cells making up our Blood are the White Blood cells, Red Blood cells and Platelets:
There are about one billion red Blood cells in a few drops of whole Blood.
Red Blood cells live about 120 days in our bodies.
Red Blood cells can be stored under normal conditions for up to 42 days.
Frozen red Blood cells can be stored for ten years, and more
