What: "Platelets are like microscopic circulating band-aids, constantly looking for leaks in the vascular system and then instantaneously plugging these bleeding sites by sticking to the wound (a process called adhesion), becoming activated locally, and then attracting other circulating platelets to build an impermeable clump (a process called aggregation) at the exact point of damage. This protective mechanism, which is a desirable function of platelets, is called hemostasis"
