HCO3

Definition

HCO3, or bicarbonate, is an important component of the body's pH buffering system. It helps maintain acid-base balance in the blood and other bodily fluids.

5 Must Know Facts For Your Next Test

1. HCO3 levels are critical in assessing respiratory function and metabolic processes.
2. Normal blood bicarbonate levels range from 22 to 26 mEq/L.
3. HCO3 acts as a buffer to neutralize excess acids in the body, particularly carbonic acid formed during respiration.
4. Altered HCO3 levels can indicate respiratory or metabolic acidosis or alkalosis.
5. Dietary intake, kidney function, and lung efficiency can all affect bicarbonate levels.

Related terms

pH: A measure of the acidity or alkalinity of a solution, with 7 being neutral and lower values more acidic.

Acidosis: A condition where there is too much acid in the body fluids, often reflected by low blood pH and low HCO3 levels.

Alkalosis: A condition where there is too much base in the body fluids, often indicated by high blood pH and elevated HCO3 levels.
