why does our blooddddd/?

why does blood clot?
please give a reallyyyy good detailed answer. very very very needful right now.
Answer:
it is an automatic response when we have a blood vessel break, or a cut, the brain sends messages to our neuron pain receptors via the nervous system causing the platelets in our blood to coagulate around the broken tissue and seal it,causing the clot, it is the body's natural defense reaction against further damage
Well, there is really only one answer. So when you cut yourself you don't die. Do you also want to know how blood clots?See pdf in source.
It is a complicated series of chemical events. Here is a diagram of the clotting cascade:http://www.frca.co.uk/images/clotting_ca...
