Across
  1. 1. decline in arterial PO2 and arterial oxygen saturation
  2. 3. the oxygen consumption of a tissue is dependent on blood flow to that tissue and the amount of oxygen extracted from the blood by the tissue
  3. 5. causes an enormous increase in intrathoracic pressure
  4. 9. pressure exerted by the proteins in the blood
  5. 11. the ventricle responding by contracting more forcefully
  6. 13. excess carbon dioxide being released from bicarbonate buffering of lactic acid
  7. 14. the product of heart rate and stroke volume
  8. 15. the movement of fluid out of the capillaries is dictated by the pressures inside the capillaries
  9. 16. shortness of breath
  10. 17. happens when plasma volume is reduced
  11. 18. an increase in the fraction of cardiac output directed to the vasodilated skin to facilitate heat loss and increase body temp
  12. 20. the fluid that carries oxygen and nutrients to the tissues and clears away waste products
Down
  1. 2. overbreathing
  2. 4. the degree to which the myocardium is stretched before it contracts
  3. 6. highest value achieved in an all out effort
  4. 7. measured by taken the pulse at the radial or carotid artery
  5. 8. between 55% and 70% VO2max
  6. 10. optimal HR for meeting the circulatory demands at that specific rate of work
  7. 12. parallel coactivation of both the motor and the cardiovascular control centers of the brain
  8. 19. the pressure against the heart that pumps blood by the peripheral resistance in the large arteries
