Kira got out of breath while performing, and began breathing slower and deeper after the performance. Which of the following bes
kotegsom [21]

Answer:

(A)

Explanation:

In question number one, it is important to understand that during exercise, the oxygen hemoglobin dissociation curve shifts to the right. This is also confirmed by the fact that the patient, Kira is also breathing slowly. CO2 builds up in the both as patients begin to hypo ventilating. Most likely this patient in in a state of respiratory acidosis. But, it is important to understand that when the curve shifts to the right in this situation, you have decrease affinity of Hb for O2, meaning that the O2 does not want to bind to the hemoglobin. It instead is gonna wanna go straight to the tissues so that the tissues can get oxygen during high exercise states like this one. If the tissues don't get oxygen then you would have elevated lactic acid production in the tissue and the body would go into a sever state of lactic acidosis. So during excercise and increased CO2 content in the blood due to hypoventilation post excercise, our body's natural mechanism is to dump all the oxygen we get directly to our tissues and bypass the hemoglobin that is circulating in our vessels. So that being said you should be able to answer the question above. The hemoglobin would be less saturated with o2 in this case.

Hope this helped !
