The level of pH (potential of Hydrogen) is very important for maintaining our lives and well-being. For example, the normal pH for our blood is between 7.35-7.45 (an average of 7.4), any deviation from this very small range could mean serious trouble. For this reason we emply buffer systems. Buffer is a substance that counteracts changes to the pH level. Examples for the buffer systems are: - Phosphate buffers - bicarbonate buffers - protein buffers (like haemoglobin).

∙ 9y agoAll organisms have a range of pH levels that they can survive at. The main reason for this is that the enzymes they use for their many metabolic reactions have an optimum pH level that they operate at. If the pH is too far from this, the reaction may take considerably longer or field less than desirable results.
Also, sudden changes in pH level can harm organisms. Most living things have trouble coping with sudden change. For this reason, many have buffer solutions in their cell vacuoles, which are weak acids or bases used to neutralize strong acids or bases to prevent sudden changes in the pH.

What organ filters blood to maintain a constant blood PH level?
kidneys
Does homeostasis effect pH?
It does, because pH needs to be regulated in order to keep enzymes at an optimum rate of reaction. They can be denatured by extremes in pH. The blood pH is made more acidic by carbon dioxide. This is caused by increased metabolic rate in the body, since carbon dioxide is a waste product of respiration. This would make the blood too acidic, and denature enzymes. So, the body has a way of maintaining a relatively constant pH. This is maintained because by the combination of carbon dioxide with water, forming hydrogen carbonate ions, which are acidic. in this way, homeostasis effects pH.
What is the role of buffers in the human body systems?
Buffers resist pH changes in cell cytoplasm, and in extracellular fluids.
What does a buffer regulate?
The pH ( or the concentration of H+ ions) of the medium. A buffer is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. Its pH changes very little when a small amount of strong acid or base is added to it and thus it is used to prevent any change in the pH of a solution . Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. Many life forms thrive only in a relatively small pH range so they utilize a buffer solution to maintain a constant pH. One example of a buffer solution found in nature is blood.
What happens to the buffer a pH capacity?
The buffer maintain the pH constant.

Explain why orange juice does not create acid blood?
There is a buffer in our blood that keeps the pH of our blood at around 8.2
The pH of human blood is about?
The pH of the blood is slightly alkaline. Although dissolved carbon dioxide forms a slightly acidic solution in the blood plasma, there are buffers present. These help keep the blood at a constant pH of between 7.35 and 7.45 .
Why does pH of blood remain constant?
Due to the presence of buffers like plasma
What chemical species keeps H3Oplus in blood at the appropite pH?
The most important buffer system in blood is H2CO3/HCO3- (carbonic acid / bicarbonate) at pH = 7.35 and 37oC

What role does exhalation of carbon dioxide play in maintaining constant blood pH?
When there is too much CO2 it combines with H2O to make carbonic acid. It also disassociates into 3 hydrogen ions and this raises the pH in the blood.
What is the benefit carbonic acid?
Carbonic acid helps in buffering system of blood. They help in maintenance of the constant body pH.
