\.Select all that apply to allowing O, transport through blood.
Erythrocytes containing here groups increasing oxygen transport.
Oxygen dissolving in the water within blood
Dissolved proteins increasing oxygen solubility in blood. - ANSWERS✔-

Dissolved proteins increasing oxygen solubility in blood.
\.You take a trip to Denali National Park in Alaska and hike up 5,500 m in elevation
toward the peak of Denali Mountain where the elevation is so high that
atmospheric pressure is half that at sea level
If O2 comprises 21% of all particles in the atmosphere, what is the partial
pressure of O2 at the highest point of your hike?
Hint: pressure is 1 atm at sea level.
Po2 = 0.210 atm
Po2 = 1.00 atm
, Po2 = 0.420 atm
Po2 = 0.105 atm - ANSWERS✔-Po2 = 0.105 atm
Dalton's Law states: P 02 = (% 02 in air) * (Total pressure)
Since the altitude makes it so that the pressure is 0.5 atm, then:
P 02 = 21% * 0.5 atm = 0.21 * 0.5 = 0.105 atm
\.Using the above Hemoglobin-Oxygen Saturation curves explain why it is
important to have a non-linear oxygen-dissociation curve.
Less O2 is released in areas of the body where O2 concentrations are the lowest.
More O2 is released in areas of the body where Oz concentrations are the lowest.
More O2 is released in areas of the body where O2 concentrations are the
highest. - ANSWERS✔-More O2 is released in areas of the body where Oz
concentrations are the lowest.
Using the graph we notice that in areas where the partial pressure of oxygen (Po2)
is LOW (like in areas of tissue doing large amounts of aerobic activity and
consuming oxygen), the saturation of oxygen in hemoglobin (Hb) is also LOW
meaning most of the oxygen bound to hemoglobin dissociates in areas where
there is not a lot of oxygen present.
This allows tissues, like muscles, to receive more oxygen when they begin using up
more and more of the surrounding oxygen while running for example.
\.Select the correct order of changes that occur in the air tract when the
diaphragm
