Transcript

  • 1. LOGO Respiratory System Arba P. Ramadani
  • 2. Respiratory System Structural Upper Function Lower Conducting zone Respiratory zone
  • 3. NOSE
  • 4. NOSE Eksternal bony&cartilaginous framework function? Internal nasal cavity, vestibule, & septum
  • 5. PHARYNX levelfive.com/ZINA/IMAGES/Anatomical/pharynx.jpg
  • 6. PHARYNX Function?? Regio: nasopharynx, oropharynx, laryngopharynx
  • 7. LARYNX
  • 8. LARYNX Voice box Short passageway, connect the laryngopharynx with the trachea Larynx wall 9 pieces cartilage eg. epiglotis
  • 9. TRACHEA
  • 10. TRACHEA Windpipe, tubular passageway for air Layers: mucosa, submucosa, hyaline cartilage, adventitia C-shaped cartilage ring control diameter change maintain efficient airflow
  • 11. BRONCHI graphics8.nytimes.com/.../health/adam/1103.jpg
  • 12. LUNGS www.avastin.com/.../lung/learn/develops/index.m
  • 13. LUNGS Paired cone-shaped organ Pleural membrane parietal p., visceral p., p. cavity Lobes 3 lobes on right & 2 lobes on left Blood supply pulmonary&bronchial arteries Hypoxia ventilation-perfusion coupling
  • 14. Terminal bronchioles Alveolar sacs Alveolar duct Alveoli
  • 15. webanatomy.net/.../respiratory/alveolar_sacs.jpg
  • 16. RESPIRATION Pulmonary ventilation External (pulmonary) respiration Internal (tissue) respiration Respiration
  • 17. PULMONARY VENTILATION Air moves into or out of lungs pressure differences air Inhalation contraction of diaphragm (75%) & external intercostals (25%) lungs expand lung vol >> decrease lung pressure Exhalation passive process inspiratory muscles relax lung vol << alveolar pressure increases
  • 18. Factors affecting pulmonary ventilation Surface tension of alveolar fluid Compliance of the lungs Airway resistance
  • 19. P O2 & P CO2
  • 20. Rate of pulmonary &systemic gas exchange Partial pressure difference Surface area available Diffusion distance Molecular weight & solubility
  • 21. Breathing Pattern Eupnea Costal breathing/ shallow/chest Diaphragmatic breathing / deep
  • 22. LUNG VOLUME
  • 23. Transport O2 & CO2
  • 24. Affinity Hb-O2 Acidity (pH) PCO2 Temperature BPG
  • 25. Control of Respiration 1 2 Medullary Rhythmicity Area Pneumotaxic Area 3 Apneustic Area
  • 26. Regulation of the respiratory center Cortical influence Inflation reflex Propioceptor Chemoreceptor Others
