Blood Clotting
Initiated by Extrinsic mechanism
Substances from damaged tissues are mixed with the blood,
Intrinsic mechanismBlood itself is traumatized
Affected by more than 30 blood substances. Prothrombin – essential clotting mechanism.Platelets - initiates blood clottingVitamin K – needed to produce prothrombin.

Blood Clot
Requirements:thrombin
calcium ions (Ca2+)
clotting factors
Components: Platelet plugs enmeshed in a network of insoluble fibrin molecules

Allergic Reaction
An over reaction of the body’s defense.
Response to invader.
Triggered by Allergens (antigens).
Can be caused by anything.
Can be life threatening.

Summary
Blood clotting is a protective mechanism to avoid blood loss,Immune response is body’s defense. Allergic reaction is an exaggerated response to antigen.Hormone release is to sustain system functions.Four functions are with special association.
