Which system assists in maintaining pH balance in the body?

• A. Respiratory System
• B. Circulatory System
• C. Digestive System
• D. Endocrine System

Answer: (A)

The respiratory system plays a crucial role in maintaining pH balance in the body through the regulation of carbon dioxide (CO2) levels. When CO2 is produced as a waste product of cellular metabolism, it enters the bloodstream. The respiratory system manages the elimination of CO2 via breathing. If CO2 levels rise, it can lead to increased acidity in the blood (lower pH). To counteract this, the body increases the rate and depth of breathing, allowing for more CO2 to be exhaled, which helps restore pH balance to its optimal range. Furthermore, this system works in tandem with the kidneys to regulate bicarbonate levels, which also contribute to the acid-base balance in the body. Thus, the respiratory system is essential for immediate adjustments to maintain the body's pH within the narrow range necessary for proper physiological functioning.
