BIPN 102 Chris Childers Dr. Fortes Fall 2009 Lecture 7 – 10/9 Lecture 8 – 10/12 Lecture 9 – 10/14 Gas Exchange: N2O, O2 (physiological and pathophysiological conditions), CO, altitude Diffusion vs. Perfusion Limited Exchange Perfusion/diffusion matching Regional differences in the lung Local & systemic changes to high altitude exposure Gas solubility Myoglobin Hemoglobin (structure, sigmoidal curve, cooperativity, curve shifting) Effects of CO2, pH, Temp, 2,3 DPG Diffusion… On the three graphs below. . A. Label the axis (time, partial pressure) B. On graph A, draw the diffusion graphs of N20, CO, and normal O2 C. On graph B, draw the diffusion graphs of normal O2, abnormal O2, and grossly abnormal O2 D. On graph C, draw the diffusion graphs of normal O2, abnormal O2, and grossly abnormal O2 at altitude Utilizing the graphs above, indicate whether the following situations will be (D) diffusion-limited, or (P) perfusion- limited… _________ N2O __________ CO __________ A normal human being at sea level, resting
