What happens with blood loss?

Why do blood clots form?
Bleeding disorders often develop when the blood can’t clot properly. For blood to clot, your body needs blood proteins called clotting factors and blood cells called platelets. Normally, platelets clump together to form a plug at the site of a damaged or injured blood vessel. The clotting factors then come together to form a fibrin clot. This keeps the platelets in place and prevents blood from flowing out of the blood vessel.
