What happens to the breathing rate if blood concentration of oxygen decreases?
Decreased breathing rate > more Co2 and less O2 in blood > more acidity > Lower PH level
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 Ph regulate breathing?
It doesn't. pH is a measure of acidity or alkalinity of a substance, breathing is taking oxygen out of air and putting out carbon dioxide.
Why does pH of blood remain constant?
Due to the presence of buffers like plasma
What prevents rapid large swings in pH?
buffer
Would a person who is hyperventilating suffer from alkalosis or acidosis?
When the pH level in blood falls below 7.35, then acidosis has occurred. On the other hand, when the pH in blood goes above 7.45, then that alkalosis has occurred. Loss of carbonic acid due to rapid breathing can cause alkalosis.
What does medullary breathing centers directly sense and responds to?
blood PH and Co2 concentration
What happens to the breathing rate if blood concentration of oxygen decreases?
Decreased breathing rate > more Co2 and less O2 in blood > more acidity > Lower PH level
How is blood pH maintained by the respiratory system?
Respiration controls the amount of carbon dioxide in the blood. If respiration slows, CO2 increases, causing a respiratory acidosis. If respiration quickens or deepens, CO2 decreases, promoting a respiratory alkalosis. This is helpful if there is another process going on that impacts the pH of the blood. For instance, in diabetic ketoacidosis, the pH decreases in the blood due to the production of ketoacids. The respiratory system responds by increasing respiration and decreasing CO2 to help bring the pH of the blood up toward normal. The pattern of breathing patients in DKA develop is called Kussmaul breathing - deep and fast. This is a classic sign of DKA.

Which gas stimulates us to breathe?
breathing is controlled by the level of co2 in the blood, (not due to the fact that there may be low amounts of o2), there are chemoreceptors that measure the pH level of the blood, remember that co2 can be transported in the blood as carbonic acid, thus this acid lowers the pH. if a low pH is detected, it sends nerve impulses to our brain, that stimulates us to breathe in an effort to get rid of the co2.
What would low carbon dioxide in blood do?
Slow down breathing, because pH would rise.
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.
What monitors the pH levels in the blood?
Breathing, CO2 and O2
Your CO2 level has dropped from 25 to 11 What does this mean?
It means that you are hyperventilating. Some times this is the body's response to what is called acidosis, which is a low blood PH. Since carbon dioxide is an acid in the body, the body will increase the breathing rate to "blow off" some CO2 and raise the blood's PH. This is the body's fastest way to balance blood PH. If we are too acidic, then we blow off more CO2, if we are alkalotic, we slow our breathing down and retain CO2, thereby decreasing our blood PH. Another (slower) regulator of blood PH are the kidneys. When we are chronically acidotic, our kidneys will retain bicarbonate to raise the blood PH. When we are chronically alkalotic, our kidneys will excrete bicarbonate in the urine, thereby lowering the PH.
