A
Vessel spasms
Platelet becomes sticky
Clotting cascade initiated
Thrombin - fibrinogen - fibrin
Fibrin web over injured area forms clot

Fibrin + platelets = clot
3
Q

A
Stationary clot
Usually in leg veins (DVT)
Can form in atria during Afib
5
Q

A
Traveling clot
Pulmonary embolism (starts in legs normally)
CVA ( starts in heart normally)
MI
6
Q
Anticoagulant
A
Prevent clot formation
7
