Carbonic acid( H2CO3 ) and its conjugate base bicarbonate[ HCO3(-) ].
it is the buffering system in ocean

Circulatory system
yes
I believe the bodies transportion system is the cardiovascular system :)

The major plasma buffering system in the body consists of bicarbonate (HCO3-) and carbonic acid (H2CO3). This system helps maintain the pH balance in the blood by shifting between bicarbonate and carbonic acid in response to changes in hydrogen ion concentration.
Buffering system is the physiological system that function to keep pH within normal limits.
