Question 51

hemostasis

Answer 51

process that prevents hemorrhage (bleeding)

Question 52

3 steps of hemostasis

Answer 52

1. vascular spasm 2. platelet plug formation 3. blood clotting

Question 53

vascular spasm (step #, what is it, effect)

Answer 53

first step in hemostasis - chemical signals released by damaged smooth muscle/activated platelets OR reflexes initiated by pain receptors, lead to spasm of smooth muscle - this stems bleeding until other mechanisms activate

Question 54

platelet plug formation (step #, what is it, effect)

Answer 54

second step of hemostasis 3 steps - platelet adhesion - platelets stick to injury - platelet activation - release granules which leads to vasoconstriction and ADP release - ADP release makes platelets sticky, they clump and form a platelet plug

Question 55

blood clot formation (step #, what is it, effect)

Answer 55

third step of hemostasis - blood clot = platelet plug + insoluble protein fibres - coagulation - process of blood clot formation - requires clotting factors like calcium - two pathways - extrinsic, intrinsic

Question 56

if clots for too easily, can lead to

Answer 56

thrombosis

Question 57

when clots block small vessels

Answer 57

embolism
