51
Q

hemostasis

A

process that prevents hemorrhage (bleeding)

52
Q

3 steps of hemostasis

A
  1. vascular spasm
  2. platelet plug formation
  3. blood clotting
53
Q

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

A

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

54
Q

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

A

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

55
Q

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

A

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

56
Q

if clots for too easily, can lead to

A

thrombosis

57
Q

when clots block small vessels

A

embolism
