Which statement regarding carbon dioxide transport in the blood is true? HCO3- dissociates into CO2 and O2. H2CO3 dissociates into H+ and HCO3-. 93% remains dissolved in plasma as CO2. The chloride shift occurs when Cl- moves out of RBCs in exchange for HCO3-. 25% is converted to H2CO3 by carbonic anhydrase.

Referring to the loading and unloading of oxygen from hemoglobin (as illustrated in the figure), which of the following statements is correct? Oxygen Dissociation Curve.png Group of answer choices When a person in ventilating at rest, 75% of hemoglobin is still oxyhemoglobin The percent saturation of hemoglobin is higher at higher partial pressures of oxygen A decrease in the pH of the blood would promote unloading oxygen from the hemoglobin All of these are correct
A plasma increase of which of the following will cause a leftward shift of the hemoglobin saturation curve? O pH O PACO2 O 2,3 BPG
Which is true about the oxygen-hemoglobin dissociation curve? A decrease in pH decreases hemoglobin affinity for oxygen A decrease in temperature increases hemoglobin affinity for oxygen Oxygen unloads from hemoglobin when tissue PO2 decreases An increase in PCO2 decreases hemoglobin affinity for oxygen All of the above
When the blood passes through the lungs, CO₂ is expelled and the hemoglobin picks up oxygen. Place the following steps in the correct order (1 = first thing to happen), assuming that it is the decreased [CO₂] during exhalation that initiates the transition. Carbonic anhydrase works to restore the CO₂/bicarbonate equilibrium, reducing the [H+] The T-state is less stabilized. Oxygen binds to the hemoglobin. Protons dissociate from the hemoglobin.
Capillary in lung) Alveoli in lung Capillary in tissue Poz PC0₂ Poz = 40 mm Hg Pco₂ = 46 mm Hg 100 mm Hg = 40 mm Hg 0₂ = CO₂ Cells in body Refer to the accompanying figure. Which statement is accurate? CO₂ will diffuse from the alveoli into the capillaries. CO₂ will diffuse from the capillaries into the tissues. O₂ will diffuse from the capillaries in the tissues to the capillaries in the lung. O₂ will diffuse from the alveoli into the capillaries. O₂ will diffuse from the tissues into the capillaries.

Sixty hours after aspirin ingestion, the patient’s blood pH has returned to normal (pH7.4). Describe how the carbonic acid/bicarbonate buffering system responded to bring thepatient’s blood pH back to normal. LeChatelier’s Principle may be helpful here. For the question above, doesn't the stopping of hyperventilation (due to the passage of time) automatically increase the CO2 concentration in blood, thus re-establishing all the "normal" equilibria, including the one with H+? How does the H2CO3/HCO3- buffer respond?
