When blood CO2 levels increase does the pH increase or decrease?
It decreases.
Hyperventilation is most likely to be accompanied by a?
decrease in blood CO2 concentration and a rise in pH
Why does blood hydrogen ion concentration decrease as the body's metabolic rate decreases?
As the body's metabolic rate decreases, the amount of CO2 that is released into the blood stream decreases as well. The reduced amount of free CO2 means that there is less interaction with H20 which in turn reduces the amount of carbonic acid in the blood stream. With less carbonic acid, there is less neutralization, then there is less free hydrogen ions in the blood stream.
Place where blood changes from low CO2 to high CO2?
veins
How does hypoventilation affect pH?
Hypoventilation is causes an increase in CO2 (carbon dioxide) in your blood. This is caused by the lack of breathing, or obtaining oxygen, (on the contrary, hyperventilation is when your body is gaining too much oxygen - people tell the hyperventalator to breath in a brown paper bag to allow CO2 to bind to hemoglobin). 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).

It decreases.

Why does Hyperventilation cause apnea?
WIth hyperventilation there is a decrease of CO2 in the blood and lungs. Lowering CO2 concentration increases the time before the respiratory center becomes stimulated.
Does increase in blood co2 increase or decrease respiratory rate?
When your oxygen levels go up and carbon dioxide levels in the body go down this will cause your heart rate to speed up. This is caused by the blood vessels opening and the heart working harder to pump the blood.
Why do you yawn when you are sleepy or drowsy?
while sleepy CO2 accumulation increase and to get rid of it we yawn.
What is the respiratory mechanism of pH control?
The respiratory system helps control the acidity of the blood by regulating the elimination of Carbon Dioxide (CO2) and Water (H2O).These molecules are exhaled with every breath.H2CO3 --> H2O + CO2(carbonic acid)The brain is sensitive to blood CO2 levels and pH.A significant increase in CO2 or decrease below pH 7.38 of arterial blood- causes breathing to increase (in rate and depth)- results in hyperventilation- more CO2 is exhaled- eliminates CO2 - reduces H2CO3 and H+ concentrations- increases pH back to normalA significant decrease in CO2 or increase in pH- causes breathing to decrease- results in hypoventilation- less CO2 is exhaled- increases CO2 - increases H2CO3 and H+ concentrations- decreases pH back to normalRespiratory mechanism (depth and rate of breathing) controls CO2CO2 in solution is an acid.Partial Carbon Dioxide (PaCO2) levels in Arterial Blood Gas (ABG).Higher PaCO2 causes acidosis (lower pH), or neutralizes alkalosis.Lower PaCO2 causes alkalosis (raises pH.), or neutralizes acidosis.
Why does the arterial Po2 decrease with emphysema?
emphysema is a condition of loss of elasticity of the alveoli where exchange of oxygen and Co2 occurs. The alveoli cannot efficiently exchange oxygen for Co2 so Co2 builds up in the blood. It is usually caused by chronic smoking but can be caused by other diseases/conditions.
Is a decrease or increase in CO2 in the blood the chemical stimulus that causes the cessation of breath holding?
You can not die of holding the breath. As you hold the breath, carbon bi oxide get accumulated in your blood. It is very powerful stimulant of the breathing.
What is the effect of hyperventilation on pH?
Blood pH is normally 7.35-7.45. With excess CO2 in the circulatory system, cabonic acid becomes present, which in turn decreases pH of blood. Thus, to return blood pH to a normal level, ventilation is increased to increase oxygen saturation and decrease CO2 saturation, which will then reduce the amount of carbonic acid, which will normalize blood pH.
Is it true that as ventilation increases and more carbon dioxide is removed from the blood the hydrogen ion concentration of the blood decreases?
Yes it is true. That's what doctors call sometimes respiratory alkalosis (when the pH of the blood goes higher up than...). What happens its very simple and cool. As you hyperventilate you win a lot of oxygen molecules but you also loose a lot of carbon dioxide molecules (in the physiological exchange of CO2 for O2 between the alveoli and the pulmonary capillaries). This decrease in CO2 in the blood decreases the amount of CO2 molecules dissociating into HCO3- and H+ when it interacts with the water molecules. This explains the decrease in H+ molecules and the increasing of the PH
What happens when you have dirty blood?
it is blood that has co2
How does the brain control breathing?
there's a part of this brain called the respiratory system and if i am not mistaken it is located in a part of the brain called pons and the medulla oblongata. the brain controls the rate of breathing by monitoring the level of carbon dioxide in the blood. CO2 by the way is the main stimulus for breathing. without it, you just stop breathing at all (so CO2 is not at all that bad). anyway, when CO2 levels in the blood is high a condition known as respiratory acidosis develops. as a compensatory mechanism the brain causes us to hyperventilate to get rid of that extra CO2. when the CO2 level is low on the other hand, respiratory alkalosis develops. as a result the brain will cause us to hypoventilate which allows for the accumulation of CO2 in the blood. CO2 is maintained at a normal range which is 35 - 45 mmHg.
