What is the pH value of human blood under normal conditions?

Key Points

• The normal pH value of human blood is 7.4.
• Human blood is slightly alkaline, with a narrow pH range of 7.35 to 7.45.
• The body maintains this pH range through various mechanisms, including buffering agents in the blood, respiration, and kidney function.
• A pH value significantly outside this range can be dangerous and may indicate a medical condition requiring attention.

Additional Information

• The pH scale ranges from 0 to 14, with 7 being neutral, below 7 acidic, and above 7 alkaline.
• The body's pH balance is crucial for optimal enzyme function and metabolic processes.
• Several factors, such as diet, respiratory function, and renal function, can influence blood pH.
• Conditions like acidosis (pH below 7.35) and alkalosis (pH above 7.45) can occur if the body's pH regulation fails.
