What does alkalosis indicate regarding blood pH?

Alkalosis is a condition characterized by an elevated blood pH, which means that the blood has become less acidic and more alkaline. The normal pH range for human blood is approximately 7.35 to 7.45. When the pH exceeds 7.45, it indicates that the blood is too alkaline, leading to alkalosis. This can occur due to various factors, including a loss of acid (for instance, from vomiting) or an increase in bicarbonate in the bloodstream.

In the context of the question, the correct answer reflects a fundamental understanding of acid-base balance within the body and the significance of pH levels. By recognizing that alkalosis corresponds specifically to elevated pH levels, one can better understand the physiological implications of pH imbalances and their potential effects on the body's systems.
