Acid–base homeostasis is the homeostatic regulation of the pH of the body's extracellular fluid (ECF). [1] The proper balance between the acids and bases (i.e. the pH) in the ECF is crucial for the normal physiology of the body—and for cellular metabolism. [1]
Intracellular pH (pH i) is the measure of the acidity or basicity (i.e., pH) of intracellular fluid. The pH i plays a critical role in membrane transport and other intracellular processes. In an environment with the improper pH i , biological cells may have compromised function.
The pH level of food influences its flavor, texture, and shelf life. [33] Acidic foods, such as citrus fruits, tomatoes, and vinegar, typically have a pH below 4.6 [34] with sharp and tangy taste, while basic foods tastes bitter or soapy. [35] Maintaining the appropriate pH in foods is essential for preventing the growth of harmful ...
A change in the plasma pH gives an acid–base imbalance. In acid–base homeostasis there are two mechanisms that can help regulate the pH. Respiratory compensation a mechanism of the respiratory center, adjusts the partial pressure of carbon dioxide by changing the rate and depth of breathing, to bring the pH back to normal. The partial ...
The use of acidosis for a low pH creates an ambiguity in its meaning. The difference is important where a patient has factors causing both acidosis and alkalosis, wherein the relative severity of both determines whether the result is a high, low, or normal pH. [citation needed] Alkalemia occurs at a pH over 7.45.

Walking slower, but farther is Dr. Redler’s preference because it keeps you in zone 2 cardio (a level of heart rate training categorized as 60 to 70 percent of your heart rate max). During zone ...
Electrolyte imbalance, or water-electrolyte imbalance, is an abnormality in the concentration of electrolytes in the body. Electrolytes play a vital role in maintaining homeostasis in the body.
