ing comes from a protein called accelerin. However, accelerin is
a neutral protein floating in the blood that has to be activated,
and of course, a protein is needed to do this. Yet most surpris-
ingly, the protein thrombin allows the accelerin to be activat-
ed, even though, as you'll remember, thrombin comes after
accelerin in this sequence. So how does such an event take
place?
A precautionary measure has been taken in the body to
that end. Under normal conditions, a quantity of thrombin is
always present in the blood. It is therefore the already present

When damage occurs in a vein
(below) the particles known as
thrombocytes (top right) release
chemicals that initiate a string of
reactions in order to prevent
blood loss. One of these reac-
tions is the production of fibrin,
which forms a network that
blocks the way for blood
cells and plasma (top

gency measure is
taken to prevent
blood loss.
