Document Summary

Po2, pco2, diffusion is proportional to solubility (co2- diffuses approx. Average female 12-16g hb/ 100 ml blood (approx. 13% difference between male and female hb conc. ) About 3ml of o2 dissolved per liter of plasma. 2% of total o2 is dissolved in blood (po2) Hematocrit: the ratio of the volume of red blood cells to the total volume of blood. There"s differences in affinity of hemoglobin to o2. Hemoglobin loads off the o2, myoglobin picks it up because affinity is higher at lower partial pressure. Of myoglobin --> can be under water for up to. 30 mins because they have great o2 storage in muscle. At higher partial pressures of o2, hemoglobin has a higher affinity for o2. Hemoglobin has low saturation at low pressures, high saturation at high pressures. Myoglobin has a higher affinity for o2 than hemoglobin. Myoglobin only binds 1 o2 molecule at a time.
