7.35-7.45.......acidosis
7...alkalosis
7.35-7.45...alkalosis
7....acidosis
Solution
1. The pH of blood (7.35-7.45) is maintained by physiological buffers in the form of
bicarbonates, proteins etc. When pH falls below normal, it means more acidic (Acidosis), while
as when pH goes above normal value, the blood becomes alkaline (Alkalosis).
Therefore, the correct answer is:7.35-7.45...alkalosis
