PATHOLOGY

Detailed explanation-1: -Bicarbonate, phosphates, and proteins work as a chemical buffer in our body fluids. They absorb extra hydrogen ions or extra hydroxyl ions released from the things we make or eat.

Detailed explanation-2: -Buffers absorb the free hydrogen ions and hydroxide ions that result from chemical reactions. Because they can bond these ions, they prevent increases or decreases in pH. An example of a buffer system is the bicarbonate system in the human body.

Detailed explanation-3: -Hydrogen ions are by-products of the metabolism of substances such as proteins, fats, and carbohydrates. These by-products create extra hydrogen ions (H+) in the blood that need to be balanced and kept within normal range as described earlier. The body has several mechanisms for maintaining blood pH.
