Bleeding into the skin. Bleeding into the skin can occur from broken blood vessels that form tiny red dots (called petechiae). Blood also can collect under the tissue in larger flat areas (called purpura), or in a very large bruised area (called an ecchymosis).
Best Answer: Blood vessels become damaged, you bleed (which washes out debris) and it fills the wound, the blood vessels constrict & blood flow slows down. Platelets in the blood stick to collagen fibres that make up the vessel wall and this acts as a plug.From this point on enzymes (proteins called clotting factors) trigger a chain of events takes place to form a clot: Prothrombin converts to thrombin, calcium is required for this.est Answer: Blood vessels become damaged, you bleed (which washes out debris) and it fills the wound, the blood vessels constrict & blood flow slows down.
