Too much exercise causes the body's pH to drop. The pH of the blood should be maintained at 7.4. If the pH drops below 6.8 or rises above 7.8, death may occur. Fortunately, we have buffers in the blood to protect against large changes in pH. Exercise can cause dangerous drops in pH, so listen when your body screams for a rest.
normal people take breaths because of a decrease in their pH. if you hold your breath your co2 levels increase and that triggers your pH to go down, which makes you take a breath.
pH is a measure of acidity...
The normal human pH is 7.35-7.45, which means that a person's breath should technically be a base. However each breath you breath out has plenty of CO2 in which is mildly acidic.
The decease in pH is caused often by an increase in C02 levels, so the body reacts by increasing the rates of respiration so as to flush out the C02 from body back into the atmosphere. In addition the renal and alimentary system increases the rate of excretion of NaBicarbonate which removes H+ from the body. C02 + H20 <=> H+ + HC03-
Adding a base the pH increases.
Increasing the temperature will cause the pH to decrease.
When you are hyperventilating or breathing at a very accelerated rate, your body is expelling carbon dioxide faster than your body can produce it. This causes the blood's pH to RISE, thus making it more alkaline, which initiates a restriction of the blood vessels. This prevents the transportation of oxygen to the brain and other areas of the nervous system so the patient tries to get more oxygen; exacerbating the problem. A solution to hyperventilation could be to breathe into a paper bag so that you are breathing in carbon dioxide and keeping the blood's pH at a normal level.
The Ph in your body would not change
H+
plants and animals of ph in every day life Ph of soil in your backyard Ph in our digestive system Ph change as the cause of tooth decay
Changes of pH in the bowel is an effect of colitis, and not the cause of colitis.
