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