-false vocal cords, true vocal cords
-2 of aryneiod cartilage
Nasopharynx
-from posterior nares to soft palate
Oropharynx
-soft palate to hyoid bone
Laryngopharynx
-hyoid bone to start of esophagus
Larynx
-laryngopharynx to top of trachea, contains hyoid anc cricoid cartilage, vocal cords and structures visible during intubation
Trachea
-11cm long, 1 inch wide, from larynx to carina, smooth muscle and C rings of cartilage, lined with psudostratified columnar epithelium
carina
-r and l bronchus dividing point, sensitive to stimulation causes cough and constriction
dead air space
-ventilation without perfusion
anatomic dead air space
-amount of air in respiratory tract that does not penetrate to alveoli
Alveoloar dead air space
-air penetrates to alveoli that is not perfused
Physiologic dead air space
-sum of both anatomic and alveolar dead air space
Left shift Oxy-hem dissociation
-alkalosis
-lower pCO2
-decreased temp
-low levels of 2,3 DPG
-Hemoglobins like myoglobin and fetal Hb
right shift Oxy-hem dissociation
-acidosis
-higher pCO2
-increased temp
-high levels of 2,3 DPG
Bohr effect
-shift in curve by changes in CO2 and hydrogen Ion concentrations of blood
Haldane effect
-effect of oxygen on co2 tranport in blood (o2 dissociation from hemoglobin facilitates the pickup of CO2
