How does the body react to increased acidity in the blood?

The body reacts to increased acidity in the blood, or acidosis, primarily through respiratory and renal compensation. When blood becomes more acidic, the respiratory system responds by increasing the rate and depth of breathing. This process enhances the elimination of carbon dioxide (CO2), which decreases the concentration of carbonic acid in the blood, thereby helping to neutralize the acidity.

Additionally, the kidneys play a crucial role by excreting excess hydrogen ions (H+) and reabsorbing bicarbonate (HCO3-), which acts as a buffer to maintain pH balance. By utilizing both the respiratory and renal systems, the body effectively regulates pH levels and mitigates the effects of increased acidity.

This integrated response highlights the importance of homeostasis in maintaining optimal physiological conditions.
