Acid-base homeostasis
Acid-base homeostasis
Acid-base homeostasis (pronounced as: a-sid-bays ho-me-o-stay-sis) is the part of human physiology that regulates the balance between acids and bases in the body fluids. The process is crucial for the body's normal functioning and survival.
Etymology
The term "Acid-base homeostasis" is derived from three words. "Acid" and "base" are English words, referring to the two types of chemical species that the process regulates. "Homeostasis" is derived from the Greek words 'homeo' meaning 'similar' and 'stasis' meaning 'standing still', which together imply 'staying the same'.
Function
Acid-base homeostasis maintains the pH of the body's fluids within a narrow range, between 7.35 and 7.45. This is achieved through a series of complex biochemical reactions and physiological mechanisms, including respiration and renal function.
Related Terms
- Acidosis: A condition characterized by an excess of acid in the body fluids.
- Alkalosis: A condition characterized by an excess of base in the body fluids.
- Buffer solution: A solution that resists changes in pH when acid or base is added.
- Respiratory acidosis: A condition that occurs when the lungs can't remove enough of the carbon dioxide produced by the body.
- Metabolic acidosis: A condition that occurs when the body produces too much acid or when the kidneys are not removing enough acid from the body.
