BLOOD THAT HEALS WOUNDS

You must have observed that a slight skin wound stops bleeding spontaneously after a little while. This, in fact, is quite thought provoking since, under normal conditions, a liquid flowing from a hole cannot possibly stop flowing of its own accord. To have a better understanding of this fact, suppose that you have a balloon filled with water. If you make a little hole in this balloon using a needle, water will leak out of the balloon. Will it stop leaking after a while with no intervention of yours? Of course not. All the water will keep leaking until the balloon runs out of water. This applies to all liquids in closed spaces. Blood moves through a closed circuit of veins and leaks out in case of even a slight cut. However, it is of great importance for our health to stop its flow. You may have heard of people who die of excessive blood loss in accidents or operations. Well then, what causes blood to stop flowing a little while after a wound starts to bleed? This is called blood clotting, which is one of the automatic security systems in our bodies. Some substances existing in the blood stop and close the wound. Thanks to the clotting ability of blood, excessive bleeding is prevented. As shown in the illustration on the right, some cells in the blood are informed of the damaged vein and head for that site at once. First they align themselves along the wound and obstruct the flow of blood by weaving a web. This web stiffens in time and forms what we call a scar. Now let's think together. Can this planned series of actions take place by chance? How is it that some blood cells are informed of damage somewhere in the blood vessels, which is like a gigantic world in relation to their size? Why do they strive to prevent the flow of blood? How do they know that they should close the wound in order to stop loss of blood? Who taught these cells that they should close the wound? Cells could neither have learnt all these things by chance nor could they have accomplished them on their own. Even human beings, who have intelligence, cannot possibly originate such a detailed system and teach cells what to do. Certainly, the intelligence demonstrated by these cells does not belong to them. Allah inspires them and they act according to a perfect plan. Allah informs us of the excellence in His creation as follows:
He created the seven heavens in layers. You will not find any flaw in the creation of the All-Merciful. Look again—do you see any gaps? Then look again and again. Your sight will return to you dazzled and exhausted! (Surat al-Mulk: 3-4)
