Blood Buffer
Buffer solutions are solution that tends to resist change in pH upon the addition of acid or base .They assist in neutralization reaction to an extent.Buffer solution can be acidic or basic buffer.Acidic buffer contains a weak acidic and its conjugate base .They are used to neutralize a basic solutions while a basic buffer is made up of weak base and its conjugate acid .The are used to neutralize an acidic solutions.
pH value of blood will be highly harmful to human being if it is either in acidic or basic form.This can even leads to death or it renders some organs in the body to stop working.Damage to human body is being prevented by buffer solution and this is why buffer solutions are very significant to human body.
Blood plasma is responsible for many reactions inside human body and change in its pH might cause these reactions to fail.In order to have complete reaction in the blood, the blood pH must be constant.Biochemical reactions are very sensitive to the state or nature of the blood.However, these buffers are the one responsible for prevention of mishap caused by change in pH of buffer.
regulation of blood pH
When carbon dioxide dissolves in blood ,It increases the acidic content of the blood as a result of decrease in pH value.In this case , base (alkaline) buffers come into action by mixing with the plasma of the blood and then neutralize the acidic content of the blood.The same thing applies when alkaline value of the blood increases.In this case, the acidic buffers in the blood plasma come into action.if change in alkalinity or acidity of blood plasma persist for a longer period and left unattended to,the body gets into a hazardous state and could be very fatal.
