The flashcards below were created by user lcunrod7 on FreezingBlue Flashcards. What would you like to do?


  1. what are the three levels that comprise the repsiratory center
    level 1: respiratory rhytmicity center, level 2: apneustic and penumotaxic centers, level 3: higher centers
  2. what level is the basic level of control found in medulla oblongata
    respiratory rhythmicity center
  3. what level generates contraction/relaxation cycles of diaphragm, inspiratory and expiratory centers
    respiratory rhythmicity center
  4. what level reveives input: O2, CO2, pH
    respiratory rhythmicity center
  5. what level is found in pons, adjust output of rhythmicicty centers
    apneustic and pneumotaxic centers
  6. what are the apneustic centers
    inhalation
  7. what are the pneumotaxic center
    exhalation
  8. what level is in hypothalamus and limbic system
    higher centers
  9. what level is in cerebral cortex and alter activity of pneumotaxic centers
    higher centers
  10. what are the effect of blood pressure in arterial blood pressure and respiratory minute volume
    they are inversely proportional
  11. what reflex prevents over expansion of lungs during forced breathing
    inflation reflex
  12. what reflex inhibits expiratory enters and stimulates inspiratory centers during lung deflation
    deflation reflex
  13. what is how easy lungs expand, when tension in walls decrease this increases
    compliance
  14. what can decrease compliance
    arthritis and inadequate production of surfactant
  15. what this is decreased, air does not flow easily
    compliance
  16. what is how much force is required to inflate or deflate the lungs, an increase in this will make it harder to move air
    resistance
  17. what is a disorder that restricts airflow and alveolar ventilation
    COPD: chronic obstructive pulmonary disease
  18. what is an irritated conducting passageways, leads to contraction of smooth muscle, results in edema, swelling, and increase mucus
    asthma
  19. what is inflammation and swelling of bronchial lining, leads to increased mucus, results in blocking small airways
    chronic bronchitis
  20. what is destructions of alveolar surfaces, leads to the break down of elastic tissues, results in a decreased surface area for gas exchange
    emphysema
