How does the pH of the blood change when you hold your breath?

"because your heart is pumping blood with less oxygen flowing throug your blood"
I want a better answer than the one I am about to give, but the CO2 that you are holding in raises the acidity of your blood (thus lowering the pH).

What is the stimulus to breath for a normal person?
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.
Do kidneys regulate ph of the blood?
Partially, yes. Most of the pH is regulated by respiration (how fast you breath) with the kidneys providing some fine tuning of the buffering ability of the blood.
Why does the time vary for how long you can hold your breath after hyperventilating exercising breathing into a bag?
1. We can physically try to hold on to our breath for a period of time, but the medulla oblongata will detect a drop of pH level (acidosis condition) and force a breath.
How can a change in respiration affect blood pH?
Breathing rapidly (hyperventilation) or slowly (hyperventilation) are ways the body may become unbalanced or attempt to compensate an imbalanced blood pH. The blood's normal pH is 7.35-7.45. Carbon dioxide (CO2) is acts to acidify the blood (lower the pH). Therefore, hyperventilating (deceasing the CO2 contained in the blood) increases blood pH. Inversely, hypoventilation creates a decline in blood pH.
How does the pH in the blood change with an increase in the level of CO2?
An increase in blood CO2 levels will result in an increase in carbonic acid formation, and therefore lower the pH.
If the pH of human blood becomes higher than the average pH of 7 what must have occurred and what can be done to bring the pH back to normal?
the natural pH of blood is already 7.4(above neutral 7) Blood contains natural bicarbonate buffers preventing or at least stalling and fixing change in pH. when your blood rises or drops beyond the natural pH, the chemicals in your blood naturally reacts and fixes the change. For blood's pH to spike, a strong acid or base has to be absorbed into the bloodstream. it's natural for blood to rise or fall above or below 7.4 but it usually corrects itself in a matter of minutes. Hope that helps:)
Does a buffer always hold the pH of a solution at pH 7?
No. Many buffer solutions are mildly acidic or basic. Human blood, for example, is buffered a a mildly basic pH of 7.4
How does the respiratory system control carbonic acid concentration and pH?
when there is to much carbonic acid the body increases rate and depth of respiration to reduce the co2, which reduces the carbonic acid,(water in the plasma + co2 = h2co3 . when the co2 level goes down below normal levels, respirations slow and become more shallow to retain co2 which increases the carbonic acid, and adjusts the blood ph.
What animals and humans have a pH blood factor snakes reptiles humans?
Human blood pH levels are normally between 7.35 and 7.45, but there are several factors and conditions that may change the blood acidity. Factors affecting the pH of snakes and other reptiles have not been published.
The pH of the blood is nearest to what number?
Blood pH = 7.40 (+/- 0.05) (THIS IS THE ANSWER TO THE PH OF BLOOD IS NEAREST TO WHAT NUMBER)=#7
How does holding your breath effect blood pH?
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.
How do you test the pH of blood?
Blood test. The technician will take a sample and use either a lypmus strip or put a few drps into a sterile solution that will change color to determine the pH levels.
