Critical to the clotting process, forming the temporary seal when a blood vessel breaks

Answer 23

Platelets

Question 24

Fast, localized response to reduce blood loss through clotting

Answer 24

Hemostasis

Question 25

Immediate vasoconstriction response to blood vessel injury

Answer 25

Vascular spasm

Question 26

Multistep process in which blood is transformed from a liquid to a gel

Answer 26

Coagulation

Question 27

Factors that promote clotting

Answer 27

Procoagulants

Question 28

Factors that inhibit clot formation

Answer 28

Anticoagulants

Question 29

All factos necessary are present within the blood, slower clotting, and may be triggered by negatively charged surfaces such as activated platelets, collagen, or glass

Answer 29

Intrinistic pathway of clotting

Question 30

Triggered through an endothelium-derived protein factor or factor III and can occur very rapidly

Answer 30

Extrinsic pathway of clotting

Question 31

Process in which the contractile proteins within platelets contract and pull on neighboring fibrin strands, squeezing plasma from the clot and pulling damaged tissue edges together

Answer 31

Clot retraction

Question 32

Removes unneeded clots through the action of the fibrin-digesting enzyme plasmin

Answer 32

Fibrinolysis
