What is the primary buffer system in the ECF?
A)bicarbonate/carbonic acid
B)chloride/hydrochloric acid
C) haemoglobin
D) phosphate
Refer to the acid-base abnormality that would result from severe pneumonia in which gas exchange is impaired.

Question

Quizplus · Accepted Answer

Severe pneumonia leads to a decrease in gas exchange in the lungs, resulting in an increased level of carbon dioxide in the bloodstream. This leads to respiratory acidosis, which is a condition where there is an excess of carbonic acid in the blood. The primary buffer system in the ECF, bicarbonate/carbonic acid, helps to regulate the pH of the blood by balancing the levels of carbon dioxide and bicarbonate. Therefore, Choice A (bicarbonate/carbonic acid) is the best option for this acid-base abnormality.
