Same blood as everywhere else. The difference is the gases in the blood: it enters the lungs low on oxygen and high in CO2, it leaves high in oxygen and low in CO2.
High CO2 in the blood is corrected by increasing the rate of respiration. By breathing more you take in more oxygen and let out more CO2. High CO2 in the atmosphere is corrected by photosynthesis which uses light and CO2 as energy and releases oxygen as a product.
They diffuse through the membrane.Diffusion is the movement of gaseous particles from a high concentration of particles, to a low concentration.Using your example of CO2, there is a high ammount of CO2 in de-oxygenated blood, so it travels to the alveoli through the membranes, where there is a lower concentration of CO2.Remember, near every alveoli there is a capillary, which makes this possible.
this better to say blood with high CO2 concentration is dark and blood with high CO (Carbon monoxide toxemia) is bright, so O2 saturated blood is just NORMAL.
The air we inhale comes from the athmosphere; the percentage of CO2 in the athmosphere is next to insignificant. The air we exhale comes from the cellular environment; cells give off CO2 as part of their metabolism, thus CO2 venous blood concentration is high
O2 sat on room air or arterial blood would be lower than normal. CO2 levels would be higher.
at a co2 of 100 or so the person will be confused and sleepy. The lungs taking in the oxygen are not exhaling forcefully enough to expel the co2. This is usually due to lung problems such as COPD
"high blood" is nothing without words to follow it! Unless we're referring to a package of donor blood stored on a high shelf, "high blood" needs something following it to be an actual condition. For example, one could be diagnosed with high blood pressure, high blood osmolarity, high blood sugar, high blood O2/CO2 content, etc. If there is, in fact, more to the condition you're inquiring about, do a google search. Sites like WebMD, or the like, will be helpful as well.
Baking soda does raise your blood pressure. Since Baking soda raises blood pressure and if your blood pressure is high then there will be a higher diffusion of Nutrients, O2, Proteins at the arterial end of the capillary into the Interstitial Fluid due to a higher pressure gradient and thus at the venous end of the capillary a low concentration of CO2 (produced by the cells) will diffuse from the interstitial fluid into the venous end of the capillary. So overall the dissolved CO2 in the blood will be low. So how does CO2 relate to pH? we know that CO2 combines with H2O to form Carbonic Acid; Carbonic Acid in turn disassociates to form H+ and HCO3- CO2 + H20 --> H2CO3 --> H+ + HCO3- Since the CO2 level in the blood is low there will be Less H+ in the blood and therefore the pH of the blood will be high, Causing Alkalosis.
what is considered high levels of co2
it is blood that has co2
