The pH is a measure of how acidic or basic a solution is. It indicates how many hydrogen ions (H +) are present in it. the solution The lower the pH, the more acidic: where. In the medical sense it is often at the pH value of the blood which is in healthy individuals about 7.4.
The abbreviation "pH" is derived from the neo-Latin "potentia Hydrogenii" from which translates "Concentration of hydrogen" means. The pH can range to 14 from 0 (highly acidic) (very alkaline). The following applies:
The pH plays an important role in countless, partly vital metabolic processes in the human body, for example:
The pH can be in clinical practice using a Blood gas analysis (BGA) very easy and fast determine. This is extremely important also in emergency medicine, since the pH of the blood in many cases important NOTE serves to certain diseases or disorders. Here, the doctor looks first, if the pH is higher or lower than in healthy people.
The organism does everything the pH in the blood or the Acid-base balance of the body as possible stable to keep. For this he has called Buffer systems, about in the blood and urine. This is primarily to proteins, the excess hydrogen ions can bind or - at a reduced concentration - hydrogen ions can emit into the blood. These include hemoglobin and albumin.
In addition to the buffer systems man keeps the pH of the blood - and therefore the entire body - especially on the lung and the kidneys, but also with the aid of the liver at a uniform level: firstly he breathes through the lungs, the acidic carbon dioxide from, on the other hand the kidney to the acid-base balance contribute, either by
In acidosis, the body is in a sense acidifies, For example, if the pH value in the blood due organic causes - as metabolic, kidney or lung disease - decreases.
