What condition does alkalosis describe?

Alkalosis refers to a condition where there is an abnormally high level of alkalinity or base in the blood and tissues. This occurs when the pH of the blood rises above the normal range due to a decrease in hydrogen ion concentration. As a result, the blood becomes less acidic, which can interfere with various biochemical processes in the body.

Understanding the context, when considering conditions associated with blood levels, high alkalinity can result from factors such as loss of stomach acid through prolonged vomiting or hyperventilation that results in decreased carbon dioxide levels. While the other choices pertain to different physiological issues, they do not specifically define alkalosis. Therefore, option B accurately encapsulates the essence of the condition marked by increased alkalinity in the body.
