You’re always told to apply pressure, but how does that actually staunch the flow of blood to the area?
In: Biology
You’re physically blocking the opening that blood is coming out of. Imagine you have a garden hose with water coming out. Now step on the hose with all your weight. No more water coming out right? That’s all there is to it. The hose is your blood vessels and the water is blood. You’re just blocking the way for the blood to leak out until your body’s natural clotting process kicks in or until you get medical treatment to seal the wound.
