Chapter 22, Problem 3TYK
Summary Introduction
Introduction:
The process of breathing involves the flow of air inside and outside the lungs to carry out gas exchange between alveoli and blood. This process is mainly carried of oxygen from the alveoli to the blood and to other tissue cells and expulsion of carbon dioxide from the blood to the alveoli and finally to atmospheric air.

A. Non-volatile acids are excreted by ventilation
B. Volatile acids are excreted by ventilation.

On the island of Jeju in Korea, the Heanyeo sea divers free dive to collect food in the ocean by holding their breath for long periods of time. While holding their breath they are unable to get rid of CO2. Evplsin the effects this has on their blood chemistry. (Be sure to use the buffer equation in your response )

- You 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_forwardProlonged panic attack, that is characterized by hyperventilation, can lead to: Select one: a. Respiratory alkalosis b. Respiratory acidosis C.

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.arrow_forwardA socially conscious thief has just stepped out of the drug store with a few different pill bottles.
