Using the information below, calculate the Oxygen Diffusion Driving Force (mmHg), which isthe pressure gradient that drives O₂ out of the alveoli and into the blood (calculated asPAO₂- PVO₂):Barometric Pressure at Salt Lake City, UT= 4,226 ft. (1,288 m)→→ 657 mmHg. Estimated mixed-venous PO2 of blood returning to the lungs after leaving the muscle(PvO₂) at rest, measured at Salt Lake City, UT: PvO2 = 36 mmHgO 90 mmHgO 54 mmHgO 36 mmHgO 29 mmHg

The alveolar gas equation is PAO2= FiO2 (PB-PH2O)- (PaCO2/R), where, PAO2 is partial pressure of…

Energy cost for breathing significantly decreases with respiratory conditions. True False
VO2 calculation scenario: Body mass= 102 kg, HR= 180 beats/min, SV= 110 ml blood/beat, venous oxygen content = 4 ml O2/100 ml blood. What is the VO2 (ml O2/kg/min) for this scenario? (round to the nearest tenth). Remember your answer, as you will be asked to interpret this VO2 in another question. a. 31.1 b. 776.5 c. 3.5 d. 221.8 e. 7.8
The following spirogram shows a person's respiratory volumes as measured by a spirometer. The tracing began with resting, unforced breathing for the first 25 seconds, then forced breathing to measure vital capacities. Based on these results, this individual's inspiratory reserve volume is: Volume (mL) 5500 3000 2400 1200 O 4300 mL O 2500 mL 3100 mL 600 mL 1200 mL Mw W 10 30 40 50 Time (sec) M

Oxygen uptake (Fick Equation) is determined by two variables. What are they and what do they represent
South American camelids (i.e., llamas, alpacas and vicuna) are native to the Andes Mountains. In the natural habitat of these mammals, high altitudes of more than 5,000 meters above sea level, the atmospheric PO2 is about 85 mm Hg, and the PO2 in the camelids' alveoli is about 50 mm Hg. A. Briefly explain the most likely reason why the PO2 in their alveoli (50 mmHg) is lower than the PO2 in the atmosphere (85mmHg). The composition of hemoglobin molecules in these camelids is different from that of other mammals. The following graph shows hemoglobin saturation (oxygen binding) of these llamas versus other mammals. B. Does their hemoglobin have a higher or lower affinity for oxygen compared to other mammals C. Using the information in this graph to support your reasoning, briefly explain why camelids are better adapted to survive at high altitudes compared to other mammals
Give the equation for total lung capacity. A Total lung capacity = tidal volume + residual volume B Total lung capacity = expiratory reserve volume + inspiratory reserve volume C Total lung capacity = tidal volume + expiratory reserve volume D Total lung capacity = inspiratory reserve volume + vital capacity E Total lung capacity = vital capacity + residual volume
When we change altitude, during the next few days, the body responds by adjusting Hb cooperativity. This can be accomplished by changing the concentration of 2,3-BPG in the blood. After moving from a low altitude to a higher altitude, does 2,3,-BPG increase or decrease? Explain how this affects oxygen transport capacity
Compare the results for blood oxygen concentration to the results for heart rate and breathing rate. Explain how the observed changes of each parameter are interrelated.
Which of the following is the label for the Y axis of this oxygen dissociation graph? Choose from following: (A) arterial PO2 (B) alveolar PO2 (C) atmospheric PO2 (D) percent hemoglobin saturation (oxygen) (E) percent hemoglobin saturation (carbon dioxide)
What happens to the rate of oxygen being picked up under these circumstances?   *the rate of blood flow through the lungs when cardiac output goes up (as in during exercise)*
