H3PO4 is a weak acid, and a weak acid is not sufficient for a buffer.
Phosphoric acid. H3PO4
The most important buffer for maintaining acid-base balance in the blood is the carbonic acid-bicarbonate buffer.
The blood contains buffers like bicarbonate and phosphate buffers. The bicarbonate buffer is by far, the most important.
buffer systems function mainly to regulate the acid or base balance in the body. there are 3 principal classes of buffers in the body - proteins, phosphate buffer system and the bicarbonate buffer system. however, you are asking of the organs involved. these are the kidneys and the lungs.
Buffering system is the physiological system that function to keep pH within normal limits.
H2PO4-(aq)+H3O(aq) --> H3PO4(aq)+H2O(l)
1. Bicarbonate buffer system 2. Protein buffer system 3. Phosphate buffer system
bicarbonate buffer is instant, followed by respiratory, renal, and phosphate.
Bicarbonate Buffer System (only important ECF buffer)
Phosphoric acid. H3PO4
The buffer system that operates in blood plasma is the bicarbonate buffering system. The chemical equation for this system is the following CO2 + H2O <--> H2CO3 <--> HCO3- + H+.
Buffer systems help to maintain constant plasma pH. There are three buffer systems: Protein buffer system, phosphate buffer system and bicarbonate buffer system. Among these, the bicarbonate buffer system is the most predominant. Buffer Systems function as "shock absorbers" that accept excess H+ ions or OH- ions and keep blood pH constant. For example, if there is an increase in acidity of blood due to excess HCl (a strong acid), then NaHCO3 (Sodium bicarbonate) will buffer it to a weak acid (H2CO3). HCl+NaHCO3 = NaCl+H2CO3
