Volatile acids are excreted by ventilation. OC. Hyperventilation can result in a respiratory alkalosis. D. Hypoventilation can result in a respiratory acidosis OE. Ventilation adjusts the PCO2-bicarbonate buffer system.
Individuals with cystic fibrosis produce thick mucus in the lungs, resulting in a higher-than-normal level of CO2 in the blood. What is the problem that results from higher-than-normal levels of COz in the blood? Please relate this to buffers in the blood and construct a clear problem statement.
Which of the following depend (s) on the presence of electrolytes? a. membrane polarity b. neuromuscular excitability c. maintenance of osmotic relations between cells and ECF d. blood glucose levels

Given the diagram below: A. Please explain using specific equations below how this process is relevant to the study of equilibrium. B. Why is this process an excellent example of the physiological relevance of pH and equilibrium concepts in chemistry in the biological sciences?
Carbon dioxide (CO2) is readily soluble in water, according to the equation CO2 + H2O 2 H2C03. Carbonic acid (H2CO3) is a weak acid. Respiring cells release CO2 into the bloodstream. What will be the effect on pH of blood as that blood first comes in contact with respiring cells? A. Blood pH will decrease slightly. B. Blood pH will increase slightly. C. Blood pH will first increase, and then it decreases as CO2 combines with hemoglobin. D. Blood pH will first decrease, and then it increases sharply as CO2 combines with hemoglobin.
If there were little to no Chloride in the blood, what would happen to CO2 transport and why? Select one: O a. CO2 transport would not change because chloride is not part of the carbonic anhydrase reaction O b. CO2 transport would decline because H+ would not be able to bind to hemoglobin O c. CO2 transport would decline because HCO3 wouldn't be able to exit the red blood cell thus inhibiting the carbonic anhydrase reaction O d. CO2 transport would increase because HCO3 would be able to exit the red blood cell more freely
(a) The partial pressure of CO2 in the lungs can be varied rapidly by the rate and depth of breathing. For example, a common remedy to alleviate hiccups is to increase the concentration of CO2 in the lungs. This can be achieved by holding one’s breath, by very slow and shallow breathing (hypoventilation), or by breathing in and out of a paper bag.Under such conditions, pCO2 in the air space of the lungs rises above normal. Qualitatively explain the effect of these procedures on the blood pH.(b) A common practice of competitive short-distance runners is to breathe rapidly and deeply (hyperventilate) for about half a minute to remove CO2from their lungs just before the race begins. Blood pH may rise to 7.60. Explain why the blood pH increases.(c) During a short-distance run, the muscles produce a large amount of lactic acid (CH2CH(OH)COOH; K2 = 1.38 × 10 –4 M) from their glucose stores. Why might hyperventilation before a dash be useful?
After admission to the hospital, the patient becomes acutely short of breath. An arterial blood gas (ABG) was drawn, Which of the following ABG results would you expect to see and why? a. pH: 7.46, pCO2: 35, HCO3: 24, pO2: 86 b. pH: 7.36, pCO2: 44, HCO3: 22, pO2: 97
The transportation of carbon dioxide involves a reversible reaction involving the bicarbonate ion. If this reaction was not readily reversible, then carbon dioxide would would drop, as high carbon dioxide levels cause hyperventilation build up in the tissues and become toxic would remain at a constant level, as red blood cells are frequently replaced be released in the lungs when the concentration gradient become large
