Blood clotting is a protective mechanism of the body to prevent bleeding. Our body always needs to have a balance between two systems: blood clotting and anti-clotting. If these two systems lose balance, it will cause blood vessels to become blocked and bleed. So how long does it take for normal blood to clot?

There are about 30 different substances that have been found to affect the blood clotting process. Whether or not blood can clot depends on two groups of substances: procoagulants - substances that accelerate blood clotting and anticoagulants - substances that inhibit blood clotting. The following article will help us understand more about the factors involved in the blood clotting process.
