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
