The pH scale, which ranges from 0 to 14, indicates how acidic or alkaline a material is, notes Science Buddies. The scale is based on the concentration of hydrogen and hydroxide ions. Substances with a low pH have a greater concentration of hydrogen ions, which makes the acidity greater. High-pH substances have a greater concentration of hydroxide ions and are therefore more basic, or alkaline.

The liver contains enzymes that allow it to filter and process blood, metabolize nutrients, detoxify harmful substances, make blood clotting proteins and perform many other vital functions, such as secreting bile, notes WebMD.

Liver bile requires a neutral pH to break down fats and convert proteins into amino acids, notes Scientific American. After a meal, the gallbladder pumps bile into the duodenum to keep the intestinal content at the appropriate pH for digestion, and it helps break down fats and nutrients for the body to absorb and use them properly.
