Please choose one. The platelets “know” where to bind because: they are attracted to collagen and damage exposes the collagen in the vessel walls thus activating the platelets hormones are triggered by the exposure of collagen in a non-hormonal control to signal platelet activity the collagen exposure chemically activates white blood cells who emit chemical signals of their own to activate platelets as an immune response to the damaged blood vessels vasoconstriction after blood vessel rupturing triggers the platelets to congregate at the point of damage

Defense Mechanism

Circumstances influence and compel people to behave in a certain way. One such behavior is a defense mechanism. It is employed by people to escape from unpleasant circumstances, thoughts and actions. Defense mechanisms are, thus, psychological strategies that help to avert and avoid unwanted feelings such as guilt or shame and situations such as threat and danger.
