How do kidneys and lungs maintain pH balance?

Your body keeps a life-sustaining balance of pH in your blood through a remarkable cooperative effort of the lungs and kidneys. The kidneys filter the acids into the urine while reabsorbing the bicarbonate buffers. The lungs eliminate the by-products of carbonic acid (carbon dioxide) from the body through the process of proper ventilation. In this way, the blood is maintained at a pH of 7.35-7.45, regardless of the type of nourishment taken into the system. Neither the lungs nor the kidneys perform this wonderful balancing act of life alone.

The kidneys are involved in precision filtration around the clock. The kidneys have specialized cells that measure the acidity of the blood and adjust the excretion of hydrogen ions. The kidneys also reabsorb bicarbonate, the primary base in the blood, which neutralizes acids in the blood. This process continues during sleep and activity. The author informs clients that the kidneys' efficiency prevents the buildup of acid from dietary sources.

Lungs allow rapid pH adjustment through breath control. Sensors in the brainstem constantly monitor carbon dioxide levels in the body. When acidity increases, the rate of respiration immediately increases to release carbon dioxide (CO₂). This prevents dangerous drops in pH that can occur during exercise or infection. The whole system operates automatically under a level of control where no voluntary effort is necessary.

Practical points show why diet does not affect blood pH. Your organs neutralize food acids, so that food nutrients get into the bloodstream. Even alkaline water is neutralized in the stomach. Instead, write about hydration to support healthy kidneys, and about exercise to maintain good lung function. Trust your biology, not pH myths.
