1. The Human Body Chemical Plant reactions membrane separations
filtration
pumps
valves
fluid flow
heat transfer
evaporation

2. The Cardiopulmonary System
Lungs
Heart
Blood flow

3. Lungs Membrane Separation breathe air in transfer oxygen to blood
exchange for CO2
exhale CO2
Topic relevant to:
Principles I - sophomore year
Separation Processes - junior year

4. Heart Pump Pumps blood throughout body Does mechanical work
Requires energy
Topic relevant to
Fluid Transport- sophomore year

5. Blood Flow Fluid Flow carries oxygen to organs and cells
carries CO2 away from organs and cells
important part of temperature control
Topic Relevant to:
Principles I - sophomore year
Fluid transport - sophomore year
Heat Transfer - junior year

6. Cells Small reactors burn food for energy need oxygen to burn food
C6H12O6 + 6O2  6CO2 + 6H2O + energy
Food + oxygen
CO2 + water + energy

7. Oxygen - energy relationship
Measure amount of oxygen breathed
Lungs transfer oxygen to blood
Blood carries oxygen to cells
Cells burn oxygen for energy
Calculate energy expended
4.875 kcal / liter O2

8. What you will do Measure Calculate Heart rate (beats per minute)
Blood Pressure
Breathing rate (breaths per minute)
Calculate
Oxygen consumption rate (liters / minute)
Blood flow rate
Heart stroke volume (liters / beat)
Energy expenditure
Efficiency

9. Compare
