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?

Your blood is a mix of a bunch of stuff pumped through tubes. Surrounding the tubes there’s other different stuff. Some of the stuff in your blood called platelets makes lumps when it touches the stuff called collagen just outside the tube. So if you make a hole in the tube, inside stuff and outside stuff makes lumps until the hole is blocked.
