Usually, but not necessarily. A vein is a blood vessel that is returning to the heart, so it usually has a higher concentration of CO2 than an artery. But in the case of the Pulmonary vein, it is returning to the heart from the lungs, so it has a higher concentration of oxygen than carbon dioxide.

What is earle's balanced salt solution?
it is the balanced salt solution with high bicarbonate ion concentration . Media containing this requires continuous CO2 supply .It maintains pH and osmotic pressure of cells . It is used with high CO2 demanding cells.
What is the CO2 concentration in seawater?
Approx. 2 000 micromoles CO2 (gas or ions) in 1L water.
Why is blood so sensitive to pH changes?
well...too much CO2 in the body means there's a high H+ concentration.... which means there's low pH.
What happens to water vapor concentration when carbon dioxide increases?
Co2 is a acidic gas. water turn acidic when CO2 dissolved.
Why is there a higher percentage of CO2 in the air exhaled than inhaled?
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
Place where blood changes from low CO2 to high CO2?
veins
What is caprophilic microorganism?
a micro-organism that grow best at relatively high concentration of CO2
What direction are substances said to diffuse?
if something diffuses e.g. particles through the air or CO2 out of body cells means the particles go from a high concentration to a low concentration
What is the Diffusion of gases between alveoli and blood?
The Diffusion is the exchange of oxygen (O2) and carbon dioxide (CO2) between the alveoli and the blood. So blood that is pumping through the capillaries in the lungs has a low concentration of O2 and a high concentration of CO2, in the alveoli it is high concentration O2 low concentration CO2. Therefore the 2 gases exchange across the alveoli membrane by diffusion trying to establish a concentration gradient.
How co2 particles move from the blood to the alveoli?
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.
What happens to rubisco when o2 concentration is much higher then CO2 concentration?
When ther is a higher concentration of O2 than CO2, rubisco can bind O2 in place of CO2.
Does pH control the relative concentration of CO2 in water?
No. Rather, the CO2 concentration controls the pH. Other factors control concentration, such as temperature, pressure, contamination, and availability of CO2.
What will happen to the concentration of CO2 in THE WATER if it is heated?
Solubility of CO2 in water decreases with temperature, so as temperature is increased, the concentration of CO2 decreases.
Why the blood pH in veins is more acidic?
There is more CO2 in the veins and whenever there is CO2 there is also carbonic acid which will cause the PH to be more acidic.
How would the movement of CO2 be affected if the concentration of CO2 in the lungs was equal or higher than the concentration in the blood?
If the concentration of CO2 in the lungs was higher or equal the concentration in the blood, there will be no diffusion of CO2 in the air of the lungs. The person will suffocate in this situation.
Is there more CO2 or O2 in places of low concentration?
CO2
What veins carry back to the lungs as waste?
veins take the CO2 back to the lungs as a waste.
