The pH of blood is a crucial indicator of health, reflecting the balance between acids and bases in the body. Normal blood pH ranges from 7.35 to 7.45, meaning it's slightly alkaline or basic. The body works diligently to maintain this narrow range through various mechanisms, including the lungs and kidneys. A pH level outside this range can signify an acid-base imbalance, potentially leading to health issues.
- Factors affecting blood pH: Carbon dioxide levels, electrolyte concentrations, and metabolic processes all play a role in determining blood pH.
- Maintaining blood pH: The body utilizes buffer systems, respiration, and renal excretion to regulate blood pH.
- Measuring blood pH: An arterial blood gas (ABG) test measures blood pH, oxygen, and carbon dioxide levels.
