A buffer solution is a solution which a resistible change in ph upon adding a small amount of acid or base. The h2co3 is to maintain the ph value of the body.

Since the acidity content of the body is too high, the bicarbonate maintains ph by neutralizing it.

The Buffer Solution is Applicable for Weak acid & Weak base so H2CO3 is a Weak acid Because.

How to form an h2co3? Carbon dioxide is reacting with a water molecule to form an Carbonic acid this an.

Weak acid so Present in human Blood this Acid Main part of the Buffer System in Blood.
