The Role of Probability. Basic Concepts of Probability. A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
Thus, when people hypoventilate (i.e. causing an increase in CO2) this causes the pH in your blood to decrease, making it more acidic. (and when hyperventilation occurs, O2 is increased, which causes an increase in pH - making blood more basic).
As a microbiologist I find your question fascinating, mainly because my favorite little microbes play a large part in what happens to a human body after death. Some people might find it disgusting, but if you look at it from the level of the microbes, insects, and other animals involved it is just a normal part of life. Be prepared anyway because this isn't going to be pretty. First of all let's look at what happens to the human body at the time of death and soon after. At the very moment of death the heart stops beating and the lungs stop breathing. This means that the cells in the body will no longer receive blood and oxygen.
