2. Circulorespiratory System
Circulatory + Respiratory Systems

3. Oxygen

4. Oxygen

5. Oxygen releases energy

6. Oxygen
Helps cells break down food for energy (cellular respiration)

7. Cellular Respiration
Produces carbon dioxide as a waste product

8. Oxygen
Gas Exchange
-Trade oxygen & carbon dioxide

9. Oxygen
Arteries – carry oxygenated blood
Gas exchange in capillaries

10. Oxygen Review From mouth/nose, to trachea (windpipe)
To bronchi, to bronchioles, to alveoli
Alveoli – gas exchange, oxygen to blood
To heart, to arteries, to capillaries
Capillaries – gas exchange, oxygen to cells

11. Carbon Dioxide
Veins – carry carbon dioxide blood

12. Carbon Dioxide Gas exchange in alveoli
-carbon dioxide and oxygen traded

13. Oxygen Review Carbon Dioxide Review
From mouth/nose, to trachea (windpipe)
To bronchi, to bronchioles, to alveoli
Alveoli – gas exchange, oxygen to blood
To heart, to arteries, to capillaries
Capillaries – gas exchange, oxygen to cells
Carbon Dioxide Review
From cells to capillaries (gas exchange) to veins
From veins to heart to capillaries to alveoli
Alveoli – gas exchange, carbon dioxide to lungs
To bronchioles, to bronchi, to trachea
Exhaled from mouth/nose

14. Review Gas Exchange Blood Vessels In alveoli (lungs)
In capillaries (between arteries & veins)
Blood Vessels
Arteries – carry oxygenated blood
Veins – carry carbon dioxide blood
Capillaries – gas exchange
