The blood clotting system is an extraordinary phenomenon that occurs through the
activity of a series of enzymes. Each enzyme must be in the right place and go into
action at the right time. Countless enzymes work just as if they knew where they had
to be, and when. This perfect cooperation and flawless operation is a blessing creat-
ed by Allah, and every detail is a manifestation of His might and greatness.

er enzyme called thrombin cuts two of the three links in fibrinogen's
protein chain, thus converting fibrinogen into fibrin. In other words, a
previously non-active enzyme assumes an active role. Small, adhesive
parts have now appeared on the injured surface. These allow fibrin to
bond to other fibrin molecules. The result is a long chain, and the pro-
teins quickly combine and interlace with one another. This is the pri-
mary clot that forms. Subsequently, this fibrin mesh will continue to
cover the wound just like a tightly-woven fishing net.
At the same time, thrombin turns the enzyme factor XIII into fac-
tor XIIIa, which strengthens the fibrin clot. 85
The thrombin that activates fibrinogen also exists in the blood in
an inactive state known as prothrombin. This is vital, because if throm-
bin constantly coursed through the bloodstream, it would sever all the
fibrinogens. Uncontrolled clotting would occur in the body constantly.

In order to avoid any such danger, prothrombin too must be activated
by another enzyme.
