When does your blood know when its the right time to form a clot?
Its supposed to happen only when blood leaves the body. If it happens in the vessels its a pretty bad idea to clot.
My first thought was it must be the contact to oxygen that triggers the clotting process. But thats nonsense since blood tranaports oxygen, right?
So how does your blood “know” its leaving the body?

It pretty much clots when it touches anything besides these two things:
1) Other blood
2) Endothelial cells, which are special cells that line the inside of your blood vessels.
Touching basically anything else, including any other cells in your body, will kick off the clotting cascade. Blood really really likes to clot.
