Gaseous Exchange

• 1. Aveoli Diffuses O2 into the Blood
  2. Aveoli Diffuses CO2 from the Blood to the Aveoli
  3. Oxygen then Attaches to haemoglobin, is transported to muscle
  4. Carbon Dioxide is extracted by plasma & leaves the body
• Diffusion is the movement from High Pressure to Low Pressure
• Gaseous Exhcange only Occurs between Aveoli & Capillaries
