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?
In: 22
Whenever there is damage to the blood vessels, either vein or artery, a substance called tissue factor is released. That triggers platelets to start clotting.
Believe it or not, everyone has microscopic injuries to blood vessels everyday. The body forms small clots around the injuries and start to heal the vessels.
