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?
The partial pressure of oxygen in the venous blood of a human at rest at sea level is approximately 40 torrs a.) Calculate the fractional saturation of hemoglobin under these conditionsb.) What percentage of the oxygen originally bound to hemoglobin in the alveoli remained unreleased?c.) Is the residual oxygen bound to hemoglobin under these conditions of any benefit? Explain
If there are 3x10^8 alveoli in a lung with a functional residual capacity of 2.5 liters, calculate the average volume of an alveolus.
Show the values of the alveolar PO2 and PCO2 in a normal person at rest.State TWO factors that determine the alveolar PO2 and PCO2 at sea level.
Under certain circumstances, the respiratory quotient (RQ value ) for an athlete exercising intensely can rise above one. How is this possible?
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
The property of air that changes dramatically with altitude and effects breathing is ____________
Calculate the alveolar gas tension given the following FiO2 = 0.21, Patm = 700 Torr, pH2O = 47 Torr,RQ = 0.8, and PaCO2 = 38 Torr. Express answers in Torr.
Exercise can trigger symptoms of AMS due to which of the following? low partial pressure of oxygen low atmospheric pressure abnormal neural signals small venous reserve of oxygen
Alveolar ventilation remains constant when ___________ . the respiratory rate is increased while the volume of air per breath is decreased the respiratory rate and the volume of air per breath are increased the respiratory rate is decreased while increasing the volume per breath both a and c
Describe three ways in which carbon dioxide can be transported.
The partial pressure of carbon dioxide is 45 mm Hg in the blood and 40 mm Hg in the alveoli. What happens to the carbon dioxide? It diffuses into the blood. It diffuses into the alveoli. The gradient is too small for carbon dioxide to diffuse. It decomposes into carbon and oxygen.
