Slide 3 - Tekstslide

TODAY:
- Veins
- Arteries
- Capillaries

Slide 4 - Tekstslide

Blood vessels types
  • Arteries - carry blood away from the heart
  • Veins - Carry blood back to the heart
  • Capillaries - go to every cell in the body (oxygen and co2 exchange)

Slide 5 - Tekstslide

Arteries
  • Elastic walls which stretch
  • They contract and bounce back to force the blood along ('Pulse')

Slide 6 - Tekstslide

Veins
  • Are wider than arteries
  • Thinner walls
  • pressure is much lower
  • blood is sqeezed along by your muscles 
  • Flow is helped by valves 

Slide 7 - Tekstslide

Capillaries
  • Smallest blood vessels
  • Very thin walls
  • Large surface area

  • Easy for gass exchange
