How Does The Carbonic Acid Buffer System - Pass with PASS! Work?

The carbonic acid buffer system is like a smart friend who helps keep your body’s pH just right, even when things get a little crazy.

Imagine you're playing with two types of juice: one is lemonade (which is acidic) and the other is baking soda water (alkaline). When you drink too much lemonade, it makes your body feel a bit sour. Your smart friend steps in by turning some of that lemonade into baking soda water, keeping things balanced.

When you're too alkaline (like after drinking too much baking soda water), your friend turns the baking soda back into lemonade so everything stays just right.

Your body has a special team: carbonic acid and bicarbonate ion. They’re like two sides of a seesaw:

• If there's too much acid, bicarbonate steps in to absorb it.
• If there's too much alkaline, carbonic acid steps in to make things more acidic.

This happens mostly in your blood, helping you stay healthy even when you're running, eating ice cream, or doing something else that makes your body go "whoa!"
