There is a minimal if no effect on oxygen concentration in the lungsWhich of the following is incorrect? a. Hemoglobin transports oxygen through the blood from the lungs to the tissues Ob. None; all the other choices are correct c. Hemoglobin transports H+ through the blood from the tissues to the lungs O d. Lower pH increases hemoglobin's O₂-binding affinity
- factors that affect the unloading (releasing ) of oxygen more quickly from hemoglobin include all the following except a. increased pressure of CO2 b. elevated chlorine ions c. increased temp d. lowered pHMatch the Law/Effect with its definition/description A. Boyle’s Law B. Henry’s Law C. Dalton’s Law D. Haldane Effect E. Bohr Effect 1. The pressure of a gas is inversely proportional to its volume 2. A lower, more acidic pH promotes oxygen dissociation from hemoglobin 3. Hemoglobin saturated with oxygen has a low affinity for carbon dioxide 4. The concentration of a gas in a liquid is directly proportional to the solubility and partial pressure of that gas 5. The total pressure exerted by a mixture of gases is the sum of the partial pressures of the gases in the mixtureCarbon Dioxide is carried in the blood by all the following means except: a. dissolved in plasma b. as bicarbonate c. as carbonic acid d. bound to hemoglobin e. all of these methods are used to transport carbon dioxide in blood

Back to the heart and then on to the lungs for more oxygen c. Back to the heart to return to the body for more oxygen d. Back to the capillary beds for more oxygen e. Back to the brain, where the oxygen level is monitoredHemoglobin: A. binds either oxygen or carbon monoxide on its heme group B. molecules can each bind 4 oxygen molecules C. both molecules can each bind 4 oxygen molecules and binds either oxygen or carbon monoxide on its heme group D. molecules can each bind 4 oxygen molecules, and has a higher affinity for carbon dioxide E. has a higher affinity for carbon dioxide than for oxygenIf partial pressure of oxygen were about 35 MMHG and the capillaries then a. the cells would not need extra oxygen b. CO2 pressure would be very low in the cells c. it would not be able to diffuse into the tissue cells d. it would easily travel and capillaries and if used to the needy cells
