How Breath Alcohol Analysis Works

1 Comment

Alcohol shows up in the breath because it gets absorbed from the mouth, throat, stomach and intestines into the bloodstream. Alcohol­ is not digested upon absorption, nor chemically changed in the bloodstream. As blood circulates through the lungs, some of the alcohol moves across the membranes of the lung’s alveoli, into the air stored within the lungs. Because the alcohol concentration in the breath is related to the concentration in the blood, an approximate measurement can be identified when using a simple ratio formula of breath alcohol to blood alcohol which is 2100:1. This means that 2100 milliliters of alveolar air will contain the same amount of alcohol as 1 milliliter of blood

The Symbiotic Relationship of Bacteria and the Human Body

The human body is an ecosystem and in it is 10,000,000,000,000 (10 trillion) cells and 100,000,000,000,000 (100 trillion) microbes. It’s a ratio of 10:1 meaning that human beings are 90% microbial and only 10% mammalian. There are approximately 7000 different species of microbe within the intestine, approximately 700 different species within the mouth, approximately 300 – 400 different species within the vagina, and approximately 700 different species within and found upon the skin. Bacteria perform a myriad of tasks which includes regulating metabolic rates and regulating the immune system, among other various tasks
