PH balance

Definition

pH balance refers to the level of acidity or alkalinity in the body's fluids and tissues, measured on a scale from 0 to 14. Maintaining an optimal pH balance is crucial for various bodily functions, including renal health.

5 Must Know Facts For Your Next Test

1. The kidneys play a critical role in regulating the body's pH balance by excreting hydrogen ions and reabsorbing bicarbonate from urine.
2. A normal blood pH range is between 7.35 and 7.45; deviations can indicate metabolic or respiratory issues.
3. Dietary choices, such as high intake of acidic foods, can impact overall pH balance and place additional stress on renal function.
4. Chronic kidney disease (CKD) often results in metabolic acidosis due to decreased kidney function and impaired acid excretion.
5. Alkaline diets, which emphasize fruits and vegetables over meat and processed foods, are sometimes recommended to support renal health.
