Which of the following best describes the pH of blood in the human body?

The pH of blood in the human body is typically maintained between 7.35 and 7.45, which categorizes it as slightly alkaline. This range is crucial for various physiological processes, including enzyme activity and oxygen transport. The body has several mechanisms, including the bicarbonate buffer system, respiratory regulation, and renal adjustments, to maintain blood pH within this narrow range. If blood pH were to drift significantly toward the acidic end or the alkaline end, it could lead to serious health complications, thus emphasizing the importance of this slight alkalinity in maintaining homeostasis.
