WE’RE all familiar with blood … each of us contains several litres of the red stuff. Vampires find it delectable and if it all leaks out you die.
But there is far more to this vital fluid than that. Blood is a complex mixture of red and white calls, minerals, salts, hormones and much more. It transports gases around the body, removes waste products from every cell, attacks foreign invading bacteria and viruses and helps us to regulate temperature. Basically it is an all-purpose wonder fluid, a marvel of the evolutionary process – lifeblood.
