They maintain (or at least come close to maintaining) a CONSTANT pH. That is pH staying close to its original value.
Buffers are most needed at conditions ranging from weakly acidic to neutral and weakly basic, because most biochemical reactions are in that range and there is almost no buffering power in natural water with the pH range 4 till 10.
The carbonic acid and bicarbonate in the bloodstream minimize (or buffer) any trend to acidosis or alkalosis
H3PO4 is a weak acid, and a weak acid is not sufficient for a buffer.
The most important buffer for maintaining acid-base balance in the blood is the carbonic acid-bicarbonate buffer.
No acitic acid is not a bio buffer.In body only three main buffer are presentPhosphate bufferbicarbonate bufferprotein buffer(hemoglobin)
Buffers are added to systems in order to resist any minor changes in pH. EDTA is an acid, (ethylene diamine tetracetic acid), and so a buffer is used in order to maintain a certain pH even after the EDTA is added.
Buffers contain both one weak acid and its coupled weak base, that can not react with each other (they are a so-called conjugated system). When you add strong acid it will react with the base part of this buffer, when strong base (hydroxide) is added it will react with the acid.
when the capacity equals PKa where concentrations of acid and salt are the same that means Log base/acid equals zero

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

This does not make a buffer because HBr is a STRONG acid, and for a buffer you need a WEAK acid and the salt of the acid.
