One of the ways that your body helps maintain a healthy pH balance is through its chemical buffering systems. The two most common types are respiratory acidosis and metabolic alkalosis. But which one isn’t one of them? A quick look at the definition for each should tell you! For instance, respiratory acidosis is where carbon dioxide levels rise in relation to oxygen levels, which would mean that it isn’t something like renal acidification, or H+ excretion.

How Your Body Maintains pH Balance with Chemical Buffers, and Why it’s Important for You to Know About Them!
Clear understanding of this concept can help you understand more about how your body works on a day-to-day basis, and what kind of things might indicate an abnormal change in pH balance – which is definitely something worth keeping tabs on if you want to live a healthy life without having any issues down the line like kidney stones or acid reflux.
Article Content: The first thing that comes up when most people think about pH levels is whether their pool water is too acidic or alkaline.
But what’s really important is the pH balance in your body – and because of how sensitive it is, you want to make sure that this stays as close to neutral (or a value between 0-14) as possible.
This means understanding which substances are buffering or changing the acidity level of your blood for better or worse.
The key term here may be “buffers,” which will help regulate those levels by either adding more H+ ions into the bloodstream for absorption if things seem too acidic, or taking them out through kidneys when they’re not needed anymore.
There are three major groups: metabolic buffers, respiratory buffers and renal acids; let’s take a look at them one by one.
Metabolic Buffers
What are they? The body’s primary buffering system for pH is phosphate and bicarbonate, which control the blood’s acidity levels when it circulates through your lungs or liver (which has a higher concentration of these buffers). This can be done in two ways: if there’s too much H+ ions being produced in the bloodstream, either metabolic buffers will provide more to compensate OR said acids from proteins and carbohydrates will have less opportunity to react with H+. If there aren’t enough H+ ions being made, then metabolic buffer simply takes some out.
Where do they come from? Phosphates at least comes naturally as part of cellular metabolism; bicarbonates are created by the liver from CO.
How do they work? Phosphate is responsible for directly buffering acids in your bloodstream; bicarbonates buffer indirectly by neutralizing protons produced elsewhere which will then be excreted through urine or exhaled as carbon dioxide out of the lungs.
Bonus: these buffers can also come into play when you’re feeling a little too acidic, like after drinking orange juice or eating lots of citrus preserves (in which case excess potassium and calcium ions get used up to balance things back out).
Metabolic Buffers- what are they? The body’s primary buffering system for pH is phosphate and bicarbonate, which control the blood’s acid-base status.
How do they work? Bicarbonates are created by the liver from CO and can be released when protons (H+) produced elsewhere become too high in concentration, as a result of metabolic processes or through respiratory loss. When bicarbonate combines with H+, it produces water which is then excreted out of the body- this process is called carbon dioxide sparging. Bicarbonates also buffer indirectly by neutralizing protons that are generated elsewhere; these will then be excreted via urine or exhaled as carbon dioxide out of the lungs.
What happens if I don’t have enough buffers? If you’re deficient in certain chemical buffering systems, your pH levels may not regulate properly. This can lead to acidosis or alkalosis which can have a number of complications.
what is not one of the body’s chemical buffering systems?
Alkaline buffers, such as bicarbonates and ammonia
Sodium bicarbonate buffer system: same idea as with hydrogen ions but in this case they are regulated by sodium bicarbinate molecules which combine with protons (H+) so that water isn’t created and just gets excreted out of the body via urine or exhaled from lungs.
Amino acids: amino acid pH buffers work through urea production; when there are too many protons present then their excess will all bind to ammonium carbonate until it reaches a certain concentration then it will change from ammonium carbonate to urea and excreted out of the body.
Lactates: lactates are produced by muscles when they need more energy so as lactic acid is formed, protons bind with this which creates a buffer system that regulates pH levels.
