Question

Normal pH of blood is _____
(a) 7.4
(b) 7.3
(c) 6.5
(d) 7.0

Answer 1

Answer:

The normal pH of blood ranges between 7.3 to 7.45. This provides an optimal environment for the functioning of cellular enzymes.

The body has mechanisms to maintain the neutral blood pH so that systemic functions are not hampered.

In the case of acid disturbances taking place in the body, there are several ways to combat it such as bicarbonate/other buffering systems, renal system and the respiratory system.

Answer 2

Normal pH of blood is 7.4

Option: (a)

Explanation:  

• Strictly the body maintains the pH between 7.35 and 7.45. Increase of pH makes the blood more basic and decrease in pH makes the blood less acidic.

• pH is maintained by a series of different chemicals known as buffers. Buffers prevent any increase in the pH.  

• As the pH increase the amount of bicarbonate ion increases. As a result the amount of bicarbonate is excreted more in the form of ion or it is converted into carbon dioxide and excreted through the lungs.
