Decrease - as co2 is acidic
Just think about those soft drink,
as you just open and drink, its full of gases and acidicly sweet
but after those gases gone, you drink like sugar water
If the level of carbon dioxide increases, the repiratory centers are signaled to increase the rate and depth of breathing. This will result in the return of normal CO2 (carbon dioxide) and slows the breathing rate.
it is blood that has co2
Increases due to greater oxygen demands and a rising blood CO2 concentration (PCO2).
If the level of carbon dioxide increases, the repiratory centers are signaled to increase the rate and depth of breathing. This will result in the return of normal CO2 (carbon dioxide) and slows the breathing rate.
Co2 is a acidic gas. water turn acidic when CO2 dissolved.
CO2 diffuses from the blood to the alveoli and the exhalation removes the CO2 from the body.
To the best of my knowledge, blood becomes less acidic because more CO2 is removed from the alveoli through breathing. To understand this, you need to know how gas exchange mechanism in your body works. First off, when you breath, gas exchange occurs in lung's alveoli (little sacs in your lungs). The O2 that is breathed in will replace the CO2 in the blood cells. The CO2 is then pushed to the alveoli and gets blown off as you exhale. Now, how is CO2 related to blood acidity? - In the blood, CO2 and H2O react with each other to form H2CO3 (carbonic acid). See how it works now? This carbonic acid makes your blood more acidic when presence. So what happens if you breath harder and rapider? - More CO2 gets blown off. When more CO2 is removed from the circulation, the lower the H2CO3 is produced by the reaction between CO2 and H2O, the more pH increases, and the blood is less acidic. And as the CO2 level becomes too low, and the blood is too alkaline; the action reverses.
CO2 in the blood stream can be measured from bicarbonate in the blood or pCO2 (partial pressure). Normal CO2 measured from bicarbonate is 22-28 mEq/L Normal pCO2 is 35-45 mmHg
Number of stomata per unit area decreases as CO2 level increases.
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.
The questions leads towards which physiological important gases the blood contains.When the blood moves TO the lungs it has both CO2 (carbondioxide) and O2 (oxygen). However the level of oxygen is lower, and the level of CO2 is higher than with blood coming from the lungs.
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.
