A patient is hyperventilating. The "blowing off" of excessive carbon
dioxide causes a decrease in blood H+ concentration. How can the
carbonic acid buffering system function to correct this imbalance?
CO2 + H2O → H2CO3 → H* + HCO3
O H2CO3 dissociates to form more H+ and raise pH.
O HCO3- binds with H+ to form H2CO3 and raise pH.
O H2CO3 dissociates to form more H+ and lower pH.
O HCO3- binds with H+ to form H2CO3 and lower pH.
O none of the above
The carbonic acid equilibrium is shown below. Exhalation of CO2 by the lungs causes this equilibrium to shift to the ______, which causes the pH of the blood to _______.
H+ + HCO3- <=> H2CO3 <=> H2O + CO2
a) left; increase
b) left; decrease
c) right; decrease
d) right; increase
too much carbon dioxide in the blood causes it to become acidic. What is directly responsible for the drop in PH? Accumulation of CO2, accumulation of H+, accumulation of HCO3-.

High in the lungs but there is no oxygen in the muscles Equal in both the lungs and the musclesarrow_forwardConsidering the body’s pH balance is impacted by oxygen intake, why would the pH balance of blood plasma increase with rapid breathing? Conversely, why would the pH balance of blood plasma decrease if a person holds their breath?arrow_forwardYou have seen how breathing patterns can affect blood CO2 and blood pH to cause respiratory acidosis or respiratory alkalosis. Factors other than breating patterns can cause changes in blood pH. When blood pH gets out of line due to a non-respiratory problem it is referred to metabolic acidosis or metabolic alkalosis. In this case the respiratory system is called upon to try to fix the problem by adjusting breathing patterns accordingly. Use this information as you consider the next two questions. A patient comes to the emergency room having overdosed on aspirin (acetlysalicylic acid) and is in metabolic acidosis. The patient is breathing a a rate and depth of breathing that differs from normal. Predict the breathing pattern you likely would see in this patient as her respiratory system tries to help with the problem. Explain your reasoning.arrow_forward
- In an arterial blood gas result, the pH level reveals 4.5. You are aware that when the pH of the blood becomes more acidic, the respiratory center O Decreases the rate and increases the depth of breathing O Increases the rate and decreases the depth of breathing O Decreases the rate and decreases the depth of breathing O Increases the rate and increases the depth of breathing 76 77 78 79 80 81 82 83 84 8arrow_forwardWhat effect is observed on the pH of the blood in each of the following cases? a. [HCO 3−] decreases.c. [CO 2] increases. b. [HCO 3−] increases.d. [CO 2] decreases.arrow_forward(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?arrow_forward
