Which two organ systems work together to correct pH imbalances in the body?

• A. Respiratory and urinary systems
• B. Digestive and endocrine systems
• C. Nervous and muscular systems
• D. Circulatory and lymphatic systems

Answer: (A)

Verified step by step guidance

1. Identify the primary function of each organ system mentioned in the options. For example, the respiratory system is involved in gas exchange and regulation of blood pH, while the urinary system helps in excreting waste and maintaining electrolyte balance.
2. Understand how pH balance is maintained in the body. The body uses buffer systems, respiratory control, and renal regulation to maintain pH within a narrow range.
3. Consider how the respiratory system contributes to pH balance. It regulates the levels of carbon dioxide (CO2) in the blood. An increase in CO2 leads to a decrease in pH (more acidic), while a decrease in CO2 leads to an increase in pH (more alkaline).
4. Examine the role of the urinary system in pH regulation. The kidneys excrete hydrogen ions and reabsorb bicarbonate from urine, which helps to maintain the acid-base balance in the body.
5. Evaluate which pair of systems from the options provided are directly involved in pH regulation. The respiratory and urinary systems work together to correct pH imbalances by adjusting CO2 levels and excreting hydrogen ions, respectively.
