There is some bleeding from the wound and then in a few minutes the blood clots automatically and bleeding stops. This is normal. When the blood clots inside the body, inside the arteries or veins, it is a problem. Basically a clot inside an Artery blocks blood supply to a body part. For eg.

U may have heard of " Economy class syndrome" . This is a Deep vein thrombosis(DVT) in leg veins after a long flight. In situations where u are immobile for a long time the blood in the veins can clot. Thats why on flights they recommend that u move your feet up and down to keep the venous blood flow good.
