Which of the following is a buffer system contained within the blood?
A
plasma proteins
B
insulin
C
hemoglobin
D
white blood cells
E
bicarbonate
Explanation: 

Detailed explanation-1: -Human blood contains a buffer of carbonic acid (H2CO3) and bicarbonate anion (HCO−3) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. In this buffer, hydronium and bicarbonate anion are in equilibrium with carbonic acid.

Detailed explanation-2: -Bicarbonate-Carbonic Acid Buffer. The bicarbonate-carbonic acid buffer works in a fashion similar to phosphate buffers. The bicarbonate is regulated in the blood by sodium, as are the phosphate ions.

Detailed explanation-3: -The pH of blood is maintained at   7.4 by the carbonic acid – bicarbonate ion buffering system.
