gas transport
| Term | Definition |
|---|---|
| oxygen transport | 1.5% in plasma & 98.5% bound to hemoglobin |
| oxyhemoglobin dissociation curve | describes relationship btw tissue oxygen & dissociation/ binding of hemoglobin & oxygen |
| how do tissues receive oxygen | tissues w/ less Poxygen= more delivery, more Poxygen= less delivery |
| to remember | 1. gas is high to low pressure 2. affinity of oxygen to heme increases as each oxygen is bound |
| relationship btw temp. & dissociation | higher temp= faster dissociation R shift; lower temp= slower dissociation L shift |
| relationship btw pH & dissociation | lower pH= faster dissociation R shift; higher pH=slower dissociation L shift |
| CO2 transport | dissolved gas, carbiminohemoglobin, bicarbonate 70% |
