temporary platelet seal - answer✔✔platelets are activated when injury exposes collagen and
VonWillebrand factor to the blood
-these 2 factors draw platelets to injury site --> platelets activated
-releasing prothrombotic molecules which cause platelet aggregation --> clot grows rapidly
-activated platelets trigger the cascade and form thrombin and fibrin

tissue factor - answer✔✔exposed with injury to vessels and also triggers the coagulation cascade
-leading to fibrin and clot formation

coagulation panel - answer✔✔-prothrombin time (PT)
-international normalized ratio (INR)
-platelets
-activated partial prothrombin time (aPTT)
-D-Dimer
-H/H

-increase heparin to increase levels

platelets - answer✔✔come from bone marrow
-clump together at bleeding site to form a clot
-150,000 - 400,000
- <25,000 is critical - primary hemostasis
-activated by *collagen*

activated partial prothrombin time (aPTT) - answer✔✔time it takes for blood to clot
-20 - 40 seconds
-increase for someone on anticoagulants
-used to monitor effect of heparin

D-Dimer - answer✔✔<0.5
-high level means could be a clot
-pregnancy can cause increased levels

Hgb - answer✔✔12-15

Hct - answer✔✔35-45

II - thrombin
III - tissue factor: comes from injured endothelial cells
