Is the concentration of carbon dioxide higer in tissues than in arterial blood?

It contains more, at the tissues the systemic artery carries oxygen which diffuses out at a capillary bed, at the same cappillaries carbon dioxide diffuses in and travels up the venules to the systemic vein

∙ 13y agoA very situation-dependent answer, but arterial blood is very low in PCO2, while venous blood would probably be similar to tissue concentrations. Hyperventillation can decrease arterial PCO2 while increasing both venous PCO2 and tissue PCO2. Vice versa for hypoventillation.

Wiki User
∙ 13y agoBecause the muscle cells create the waste gas CO2 which is then diffused to the capillary, not the other way round

What is the concentration of oxygen in the lungs normally compared to carbon dioxide?
what is the concentration of oxygemnin the lungs normally compared to carbon dioxide
What determines in which direction carbon dioxide and oxygen will diffuse in the lungs and tissues?
Diffusion, whether of gases or some other substance, is always dependent on a diffusion gradient. Diffusion always occurs from an area of high [H] concentration to an area of low [L] concentration.In the case of the lungs:oxygen moves from a [H] concentration in the lungs/alveoli to a [L] concentration in the bloodcarbon dioxide moves from [H] concentration in the blood to a [L] concentration in the lungs/alveoliWith tissues, the situation is much the same:oxygen moves from a [H] concentration in the blood to a [L] concentration in the tissuescarbon dioxide moves from a [H] concentration in the tissues to a [L] concentration in the blood
Does the exchange of carbon dioxide depend on the concentration of oxygen in the alveoli and the blood?
No. It depends on the concentration of carbon dioxide in the alveoli and the blood. The concentration of carbon dioxide in the capillaries of the alveoli is higher than the concentration of carbon dioxide in the air, so carbon dioxide in the capillaries of the alveoli diffuses out of the capillaries into the alveoli of the lungs and is exhaled.
What is the process by which carbon dioxide is moved out of a cell?
Concentration
Why does carbon dioxide moves into red blood cells by diffusion rather than by active transport?
Do you mean why does carbon dioxide diffuse out of the cells into the bloodstream? Diffusion is the movement of particles from a region of high concentration to a region of low concentration. Carbon dioxide is present in your body cells at a high concentration because the cells are making it. The process which makes carbon dioxide in cells is respiration. This is the release of energy from food. Carbon dioxide is a waste product of respiration. The carbon dioxide molecules diffuse into the blood because there is a lower concentration in the than in the cells. This is because the blood is always moving, so the carbon dioxide is carried away and does not build up. The difference in concentration between the cells and the blood keeps carbon dioxide diffusing in the correct direction.

What is PaCO2?
The concentration of Carbon Dioxide in arterial blood. Partial (Pa) Carbon Dioxide (CO2) pressure in ABG.
Where would carbon dioxide concentration be the highest?
The carbon dioxide concentration would be the highest where the oxygen is low.
Where does oxygen pass into your blood?
Oxygen diffuses into the blood in the lungs and binds to the hemoglobin since the oxygen concentration is high and the carbon dioxide concentration is low. The blood is pumped to the body. The hemoglobin releases the oxygen to the tissues because here, the concentration of oxygen is low and that of carbon dioxide is high.
Where are the breathing control centers which detect increased arterial carbon dioxide?
Increased arterial carbon dioxide will be detected by the breathing control centers which are situated in the medulla. The medulla is the most important part of the brain.

What happens when concentration of carbon dioxide is increased?
When concentration of carbon dioxide increases, global warming increases. This causes ozone depletion.
What gas diffuses from the tissues to the blood?
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
Why has carbon dioxide concentration risen since 1860?
The carbon dioxide concentration has risen for numerous reasons, including the destruction of forests. The fewer trees and plants the are, the more carbon dioxide is the environment.
What determines whether carbon dioxide is absorbed or released by blood?
The rate at which carbon dioxide enters the cell is determined by the concentration of carbon dioxide on each side of the membrane. Carbon dioxide crosses the plasma membrane by simple diffusion.
What Blood which contains carbon dioxide and lack oxygen?
Venous blood is loaded with carbon dioxide and low in oxygen Arterial blood is rich in oxygen with little carbon dioxide
What happens to carbon dioxide when it leaves the tissues?
It is released
