Very, very temporarily--your blood carries it to your lungs, where you exhale it.
All activities release carbon dioxide in the blood stream. As long as you are alive, your cells will continue to produce carbon dioxide. Even resting or sleeping will not stop it.
increase of carbon dioxide in the tissues and the bloodstream
The gas that passes from the bloodstream into the lungs is called carbon dioxide. Carbon dioxide is transported from the tissues to the lungs via the bloodstream, where it is exhaled out of the body during respiration.
The lungs remove carbon dioxide from the bloodstream. As blood circulates through the lungs, carbon dioxide diffuses from the blood into the lungs to be exhaled out of the body.
The body eliminates carbon dioxide from the bloodstream through a process called respiration. When we breathe, we inhale oxygen and exhale carbon dioxide. The carbon dioxide is carried in the blood to the lungs, where it is then exhaled out of the body.
I wouldn't exactly characterize it as separating carbon dioxide and oxygen, however, I think the answer you are looking for is the lungs which takes up oxygen into the bloodstream and expels carbon dioxide out of the bloodstream into the lungs so we can breathe it out again.
lungs .
Movement of carbon dioxide is driffen by osmosis from and to the tissue and bloodstream. Also active transport can be used. Amount of CO2 present is monitored by means of the pH of your blood as dissolved CO2 is acidic.
it is transmittid from the brain
Carbon dioxide is released from the bloodstream into the alveoli in the lungs, to be exhaled during expiration.
Carbon dioxide is the gas that builds up in the body and increases respiration. As levels of carbon dioxide rise, receptors in the bloodstream signal the brain to increase the rate of breathing in order to expel the excess carbon dioxide from the body.
The exchange of oxygen and carbon dioxide occurs in the alveoli of the lungs. Oxygen is taken up from the air into the bloodstream, and carbon dioxide is released from the bloodstream into the air in the alveoli during respiration.
