Chapter 21.5, Problem 6QC
Summary Introduction
To review:
The change in the amount of carbon dioxide in the blood when a person hypoventilates and its effect on the pH of the blood.
Introduction:
Maintenance of pH in the blood depends on the conversion of carbon dioxide to bicarbonate ions (HCO3–). During the dissociation of carbonic acid, hydrogen ions are liberated and it acts as a buffer and reduces the pH difference. pH in the blood is greatly affected by two major changes: hyperventilation and hypoventilation.

Students have asked these similar questions
respiratory failure refers to inadequate ventilation to provide oxygen to the tissues . How would the pH change in the respiratory failure ?
Increasing or decreasing the rate of respiration alters pH by, (a) lowering or raising the partial pressure of carbon dioxide. (b) lowering or raising the partial pressure of oxygen. (c) lowering or raising the partial pressure of nitrogen. (d) a, b, and c are correct.
When a person hyperventilates, what happens to his or her blood pH? A person who is hyperventilating is often told to breathe into a paper bag. Why might this help to correct the pH imbalance?

- Oxygen is mainly carried through blood in what form?arrow_forwardWhen 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.

- (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_forwardA depressed person attempts to commit suicide by taking a whole bottle of sleeping pills.
