temp effect on gas sol in liquid | |
what type of transport is the exchange between alv cap blood & alv air | |
what type of transport is the exchange between tissue caps and cells | |
difference in H2O solubility of co2 and o2 | |
whats the diff in pO2 of periph tissues and alveoli | |
what happens to interstitial & intracellular pO2 during exercise | |
what happens to pO2 and Hb saturation as altitude increases | |
whats the Hb saturation of pulmonary art and veins | |
whats the Hb saturation of systemic art and veins | |
how many heme in each Hb | |
how many Fe++ per heme | |
how are Hb saturation and pO2 related | |
what happens to oxy-hb when pO2 decreases | |
what factors affect oxygen binding to hb | |
decrease pH --> hb effect = | |
increase pCO2 --> hb effect = | |
increase temp --> hb effect = | |
increase DPG --> hb effect = | |
