They include:
-Hemoglobin + oxyhemoglobin
=Acid/alkali K salts of phosphoric acid
The normal PH level in the human body is 7.3. The natural buffers of the human body is needed so that the blood in the human body does not become to acidic. They are Amino Acids, Proteins, Phosphate, and Carbonate and Bicarbonate.
blood
Buffers resist pH changes in cell cytoplasm, and in extracellular fluids.
Buffers help to stabilize blood pH levels by acting as a reservoir for hydrogen ions. When there is an increase in hydrogen ions, buffers can absorb them to prevent a drastic change in pH. Conversely, when there is a decrease in hydrogen ions, buffers can release them to maintain a stable pH level in the blood.
Buffers are found throughout the human body, including in the blood, intracellular fluid, and extracellular fluid. These buffers help maintain a stable pH by absorbing or releasing hydrogen ions to prevent drastic changes in acidity or alkalinity. Examples of buffer systems in the body include bicarbonate in the blood and proteins in cells.
The buffers present in blood resist small changes in pH. The most prominent are phosphate and carbonate buffers in blood.
The plasma of the blood contains buffers to help regulate the pH level of the blood. Buffers prevent drastic changes in pH by absorbing excess hydrogen ions or donating hydrogen ions when needed, helping to maintain the blood at a stable pH around 7.4.

buffers
Buffers "slow" changes in pH (they make it difficult to change pH), and for animals a constant pH (internally) is critical to survival. (A change in pH of 1 - in either direction - will kill you.)
Substances that act as buffers include bicarbonate ions in blood, phosphate ions in intracellular fluid, and proteins in cells and blood. Buffers help maintain a stable pH by absorbing excess hydrogen or hydroxide ions.
