Across
  1. 5. when the venous blood cannot return to the heart sufficiently. Often occur in the extremities after exercise with inadequate cool down
  2. 6. fluid component of the blood important for blood flow and transport of nutrients
  3. 8. the short term changes that the body systems make immediately at the start of exercise that return shortly after exercise finishes during recovery
  4. 11. thin microscopic blood vessels where gas exchange occurs
  5. 12. a large artery carrying blood to the brain where your pulse can be located
  6. 13. the measure of the amount of force the blood exerts on the artery walls during the filling phase of the heart
  7. 15. the top two chambers of the heart that receive blood into the heart
  8. 18. component of blood that fights infection
  9. 20. component of the cardiovascular system that carries oxygen, nutrients and waste products
  10. 22. defined as the odifference in oxygen content between the arterial blood and venous blood that represents that amount of oxygen that the muscles are extracting and using for energy (aVO2-diff)
  11. 28. a condition of significantly increased body temperature or overheating
  12. 29. a protein component that combines with red blood cells to carry oxygen
  13. 30. the bottom two chambers of the heart that eject blood out of the heart
  14. 31. the cardiac tissue that divides the left and right sides of the heart
  15. 32. involves two phases; diastole, the filling of blood, and systole, the contracting and ejection of blood
  16. 33. large blood vessles that carry blood away from the heart
  17. 34. the widening of blood vessels allowing for and increase in blood flow
Down
  1. 1. the part of the circulatory system where blood flows to and from the heart and the body (including skeletal muscle) to delver oxygen and take up carbon dioxide
  2. 2. the mechanisms responsible for maintaining body temperature within narrow limits
  3. 3. the measure of the amount of force the blood exerts on the artery walls during the contraction phase of the heart
  4. 4. these carry blood around the body and include arteries, arterioles, capillaries, veins and venules
  5. 7. component of blood that carries oxygen
  6. 9. blood that is carrying higher amount of blood returning from the lungs
  7. 10. the number of times the heart contracts in one minute measured in beats per minute (HR)
  8. 14. the part of the circulatory system where blood flows to and from the heart and the lungs to deliver carbon dioxide and take in oxygen
  9. 16. the measure of the amount of force the blood exerts on the artery walls (BP)
  10. 17. the amount of blood ejected from the left ventricle per minute. measured in litres per minute (Q)
  11. 19. component of blood that aids in healing and blood clots
  12. 21. blood vessels that with one way valves that carry blood back to the heart
  13. 23. the narrowing of blood vessels allowing for and decrease in blood flow
  14. 24. is made up of the heart, blood vessels and blood and works to deliver oxygen and nutrients to and remove waste products away from the body
  15. 25. the amount of blood ejected from the left ventricle per beat. measured in millilitres per beat (SV)
  16. 26. a condition of significantly decreased body temperature
  17. 27. blood that is carrying lower amounts of oxygen that is returning from the body to the heart
