dissolve a clot that has already formed

138
Q

name the 3 stages of natural clotting

139
Q

a series of interactions that result in the formation of a fibrin clot

clotting cascade

140
Q

formation of a clot can result from activation of 1 or 2 pathways which are

A

extrinsic or intrinsic pathway

Q

intrinsic pathway

A

begins with damage to a blood vessel

extrinsic pathway

begins with tissue damage, occurs outside the vessel, tissue factor and thromboplastin initiate the clorring cascade that leads to the common pathway and a clot

anticoagulants
thrombolytics

145
Q

prevents platelets from sticking together

inhibit platelet aggregation “sticking together”

147
