What's in a name?
Red or dark purple spots on the skin or mucous membrane.
What are petechiae?
This hemostatic substance released by the vascular endothelium is necessary for platelet adhesion to collage.
What is von Willebrand factor (vWF)?
These blood vessels have the thickest walls in the vascular system.
What are arteries?
Stuart factor.
What is factor X?
Factors I, V, VIII, and XIII.
What is the fibrinogen group?
A lack of dietary vitamin C may cause abnormal collagen formation in the perivascular supportive tissues resulting in capillary fragility and this hemorrhagic condition mainly of the skin and mucous membranes.
What is scurvy?
This factor in blood vessels exposed during vessel damage activates this pathway of secondary hemostasis.
What is the extrinsic pathway?
This end-product of platelet aggregation facilitates the release of platelet granular contents inducing other platelets to aggregate and stimulating vasoconstriction.
What is thromboxane A2?
Hageman factor.
What is factor XII?
Factors II, VII, IX, and X.
What is the prothrombin group?
An absence of lack of platelets may result in this generalized quantitative platelet disorder.
What is thrombocytopenia?
This substance released during vessel damage activates the fibrinolytic system.
What is tissue plasminogen activator (tPA)?
This factor is the point of convergence of the intrinsic and extrinsic pathways into the common pathway.
What is factor X (Stuart Factor)?
Fletcher factor.
What is prekalleikrein?
Factors XI, XII, prekalleikrein, and HMWK?
What is the contact group?
This disorder is a result of immunization of a pregnant female by fetal platelet antigens.
What is Isoimmune Neonatal Thrombocytopenia (Neonatal Allo-immune Thrombocytopenia (NAIT)?
These organelles represent storage granules of endothelial cells that form the inner lining of blood vessels and the heart that store and release these two principle molecules.
What is von Willebrand factor and P-selectin?
This ionized mineral plays an important role in the activation of certain coagulation factors in the intrinsic pathway.
What is ionized calcium (Ca2+)?
Fibrinogen.
What is factor I?
Aspirin, NSAIDs, and Plavix are examples of this grouping of anticoagulant drugs.
What are anti-platelet drugs?
This thrombocytopenic disorder is a result of an IgG antibody that in the presence of heparin activates normal platelets causing them to aggregate and release the content of their granules.
What is Heparin-Induced Thrombocytopenia (HIT)?
Subendothelial collagen exposed by blood vessel injury initiates this coagulation pathway.
What is the intrinsic pathway?
This factor along with tissue thromboplastin and calcium provides the initiating spark for the extrinsic pathway.
What is factor VII?
Antihemophiliac factor A.
What is factor VIII?
These two tests are the most performed laboratory procedures for the assessment of blood coagulation factors.
What are the activated partial thromboplastin time (aPTT) and the prothrombin time (PT)?
