Most CO2 is transported in the blood in the form of?
When carbon dioxide is
carried by red blood cells it is carried in part by?
integrins in the plasma membrane.
Where would you expect to find the highest
partial pressure of carbon dioxide?
in the intracellular fluid
The reason the gradients for carbon
dioxide can be smaller that those for oxygen and still meet the body's gas
exchange needs is that:
carbon dioxide is more water‑soluble than oxygen.
the respirtory center that sets the ventilation rATE IS THE
ventral resipirtory group
Expired air has a greater oxygen content
than alveolar air because
- alveolar air mixes with air in the anatomic dead space on its way
what will have increased if the oxygen‑hemoglobin dissociation curve is shifted to the right?
- Partial pressure of carbon dioxide is
In metabolically active tissues you would
- the percent saturation of hemoglobin
- will be less than it is near the lungs
If the partial pressure of carbon dioxide
is decreasing, then:
- there is an increase in the rate of the reaction converting carbonic
- acid into water and carbon dioxide
As plasma Pco2 increases, plasma pH will ___________.
As plasma Pco2 increases, both the rate and depth of
respiration will ________________________.
As plasma pH decreases, hemoglobin's O2 affinity will
You begin to hyperventilate! What happens to your plasma Pco2?
What about your plasma pH?
decrease then increase
