What are you going to do for the team?

Sprint 1 deadline = thursday! 

Make sure everything is ready in your drive folder

TODAY:

- Veins

- Arteries

- Capillaries

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)

Arteries

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

Veins

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

Capillaries

• Smallest blood vessels
• Very thin walls
• Large surface area
  
  
• Easy for gass exchange
