2.62 understand that platelets are involved in blood clotting, which prevents blood loss and the entry of micro-organisms

When you have a wound you are at risk of loosing blood and
Platelets are produced in the bone marrow- they are fragments of cells. The chemicals in platelets turn fibrigen in the blood into a solid called fiberin. A network of fibrin creates inherits red blood cells and platlets; it will then dry over to form a scab, beneath which the tissue can begin to repair.
