Show Answers:

  1. A system of the body composed of the cardiovascular and respiratory systems
    Cardiorespiratory System
  2. A system of the body composed of the hear, blood, and blood vessels
    Cardiovascular System
  3. A hollow muscular organ that pumps a circulation of blood through the body by means of rhythmic contraction
  4. The space in the chest between the lungs that contains all the internal organs of the chest except the lungs
  5. A specialized area of cardiac tissue located in the right atrium of the heart which initiates the electrical impulses that determine the heart rate; often termed the pacemaker for the heart
    Sinoatrial (SA) Node
  6. A small mass of specialized cardiac muscle fibers located in the wall of the right atrium of the heart that receives heartbeat impulses from the sinoatrial node and directs them to the walls of the ventricles
    Atrioventricular (AV) Node
  7. The superior chamber of the heart that receives blood from the veins and forces it into the ventricles
  8. The inferior chamber of the heart that receives blood from its corresponding atrium and in turn forces blood into the arteries
  9. The amount of blood pumped out of the heart with each contraction
    Stroke Volume
  10. The rate at which the heart pumps
    Heart Rate
  11. Heart rate x stroke volume, the overall performance of the heart
    Cardiac Output
  12. Vessels that transport blood away from the heart
  13. The smallest blood vessels, and the site of exchange of chemicals and water between the blood and the tissues
  14. Vessels that transport blood from the capillaries toward the heart
  15. Small terminal branches of an artery which end in capillaries
  16. The very small veins that connect capillaries to the larger veins
  17. Composed of skeletal structures (bones) and soft tissues (muscles) that work together to allow proper respiratory mechanics to occur and help pump blood back to the hear during inspiration
    Respiratory Pump
  18. A system of organs (the lungs and respiratory passageways) that collects oxygen from the external environment and transports it to the bloodstream
    Respiratory System
  19. The process of actively contracting the inspiratory muscles to move air into the body
  20. The process of actively or passively relaxing the inspiratory muscles to move air out of the body
  21. The process of getting oxygen from the environment to the tissues of the body
  22. The highest rate of oxygen transport and utilization achieved at maximal physical exertion
    Maximal Oxygen Consumption (V O2 max)
