Q

describe blood clot formation

A
  • platelets wtick to wound and to each other
  • produce a substamce that produces a soluble plasma protein = fibrogen
  • grows into tiny fibres = fibrens
  • fibrins catch rbs –> clot forms

Q

describe the the normal immune response

A

-pathogen enters
-lymphocytes sense the pathogen’s antigens and produce anitbodies for that specific antigen
- they multiple rapidly to produce more antibodies
- anitbodies bind to pathogen = kill

Q

how do antibodies kill the antigens (pathiogens)

A
  • bacteia = bursts
  • causes bacteria to stick 2gether = easier for phagocytpsis
  • neutralises toxins produces

Q

descirbe the secondary immune response = teiggered by vaccines

A

lmphacttes stay in blood and turn into memory cels, giving immunity to that specific pathogen

if pathogen reenters, they recognize it faster and mass produce antibodies quizer = quicker reaction itme

Q

artery blurt

A
  • carries blod AWAY from heart
  • O2
  • high pressure
  • thick msucle walls + thin lumen
  • walls stretch w beat to force blood forwards

Q

vein blurt

A
  • carries blood TO heart
  • != O2
  • low pressure
  • thin muscle wall + large lumen

Q

capillaries

A
  • where artery = veins
  • carry blood to all cells
  • very narrow
