Describe the path and all related steps that a molecule of oxygen would take from the air in the lungs to a muscle cell. 2. Describe the path and all related steps that a molecule of carbon dioxide could take from a muscle cell to the air in the lungs. 3. Define and provide the units for blood pressure, heart rate, cardiac output, stroke volume. 4. List the ways in which training improves the effectiveness of the cardiovascular system. 5. Calculate the cardiac output of an individual with a HR of 90bpm and stroke volume of 82ml. 6. What is the SV of an individual with a resting cardiac output of 5L/min, and Resting Heart Rate (RHR) of 45bpm?  Do you think this is a non-trained or trained individual? Why? 7. Describe the two components of blood pressure. What do they measure? 8. What is hemoglobin, where is it found, what is its purpose? 9. What are erythrocytes?  Where are they produced? 10. What is hematocrit? 11. Describe the ways in which carbon dioxide can be transported through the blood. 12. What is VO2max?  What factors influence this measure?  How is it affected by training?
