Transport of Respiratory Gases by Blood
Question | Answer |
---|---|
Most oxygen is transported bound to ___inside the red blood cells | hemoglobin |
A very small amount is carried simply dissolved in___. | plasma |
Most carbon dioxide is carried in the form of___in the plasma. | bicarbonate ion |
The reaction in which CO2 is converted to this chemical occurs more rapidly inside red blood cells than in plasma because the cells contain the enzyme___. | carbonic anhydrase |
After the chemical is generated, it diffuses into the plasma, and___diffuse into the red blood cells. | chloride ions |
This exchange is called the___. | chloride shift |
Smaller amounts of carbon dioxide are transported dissolved in plasma and bound to hemoglobin as___. | carbimino Hb |
The amount of CO2 carried by the blood is greatly influenced by the degree of oxygenated of the blood, an effect called___. | Haldane effect |
In general, the lower the amount of oxygen in the blood, the___CO2 that can be transported | more |
Conversely, as___CO2 enters the blood, it prompts oxygen to dissociate from___. | hemoglobin |
This effect is called the___. | Bohr effect |
Carbon monoxide poisoning is lethal because carbon monoxide competes with___for binding sites. | oxygen |
What 3 factors will decrease the percent saturation of hemaglobin in the tissues? | lower pH, higher temperature, increase in BPG |
