Blood Clotting Design

A couple of days ago, I accidentally sliced the tip of my finger with a sharp knife. It bled a lot for a while, but in a short time, the bleeding stopped. The bleeding probably helped cleanse any debris from the wound, but I didn’t want the bleeding to continue. If our blood did not clot, we could bleed to death from even a small injury. Blood clotting design, or coagulation, is a very complicated process that scientists have studied for years.

The process begins when a puncture to your skin injures a blood vessel exposing blood platelets to the collagen beyond the blood vessel’s lining. The platelets immediately bind to the collagen and each other, forming a temporary plug. This starts a whole series of complex chemical reactions involving proteins and enzymes called clotting factors.

A cascading series of a dozen steps must take place for coagulation to complete. The result is the creation of fibrin strands which strengthen the platelet plug and stop the bleeding. If any single factor of the clotting process is missing, the clot does not form, and the bleeding continues.

Hemophilia is a genetic defect that omits a clotting factor. It disrupts the process of blood clotting design such that people with hemophilia may bleed uncontrollably from even a small wound. This is an extremely simplified summary of the coagulation process involving a dozen factors requiring specific proteins and enzymes that must happen in a particular order.

Without blood clotting, humans and other mammals could not have survived. All of the clotting factors had to be present at the beginning of mammal and human life, meaning that the coagulation process could not develop gradually by chance. The fact that our blood clots when we are injured is another evidence of design by an intelligent Creator.
