when you use a torniquette, what happens to the blood that is sent to the blocked artery as more blood is pumped in? Does it somehow get absorbed, does it flow back or does it just stagnates there?

Blood is mostly water and your kidneys are in charge of how much water is in your blood. If there’s too much, excess water is removed as pee, if there isn’t enough, water is pulled out of other parts of the body.
The blood trapped under the tourniquet will start to go bad in the veins. That’s why it’s so important that the tourniquet is left in place until the casualty reaches a hospital. If it is taken off abruptly without the proper medications, the bad blood will stop the heart.
If the doctors know how long the tourniquet was in place, they can figure out what kind of medicine they need to remove the tourniquet safely.
