How bicarbonate buffer system works
Did you know?
The bicarbonate buffer system is an acid-base homeostatic mechanism involving the balance of carbonic acid (H2CO3), bicarbonate ion (HCO 3), and carbon dioxide (CO2) in order to maintain pH in the blood and duodenum, among other tissues, to support proper metabolic function. Catalyzed by carbonic … Ver mais In tissue, cellular respiration produces carbon dioxide as a waste product; as one of the primary roles of the cardiovascular system, most of this CO2 is rapidly removed from the tissues by its hydration to bicarbonate ion. … Ver mais The bicarbonate buffer system plays a vital role in other tissues as well. In the human stomach and duodenum, the bicarbonate buffer system serves to both neutralize Ver mais • Nosek, Thomas M. "Section 7/7ch12/7ch12p17". Essentials of Human Physiology. Archived from the original on 2016-03-24. Ver mais WebBuffers, protein or otherwise, work by consuming small amounts of acid or base added to a solution. For instance, you're constantly producing carbon dioxide, and you burn sugar and other nutrients to produce energy. While you exhale the carbon dioxide eventually, it's in your blood and other body fluids until you do so, and it's acidic.
