Document Summary

The partial pressures of o2, co2 at various points of the respiratory circuit (lungs, alveoli, capillary, rbc, tissue) What happens to alveolar capillaries in times of low o2. How gases are transported in the rbcs (myoglobin & hemoglobin) The environment that reduces hb"s affinity for o2 (ph, temperature) How o2 bound to hb or mb affects the po2 of the body. The hemoglobin saturation curve and what shifts it left or right (right = higher p50 = less. O2 affinity = lower ph & dpg interaction & high levels of co2 & cl- & high. Temperatures; left = lower p50 = more o2 affinity) Effects of no on capillaries & o2 transport. The difference between maternal and fetal hb. How co2 is transported (dissolved in the blood, as hcco3-)
