which is basically a key that can unlock a clot and if you activate that plasminogen it will start to tear these ropes apart that are the mesh work of a clod the ropes are called fibrin so when you activate the plasminogen to something called plasmon it starts to eat away at these little ropes and it can dissolve the clot so your own system is going to try to do it on the on their own but if it's a big clot probably won't be able to solve it on your own and you probably won't have a TI a you know need some help from more
