Carbon dioxide is produced as a waste product of aerobic respiration: oxygen + glucose ----> carbon dioxide + water + ATP(energy). This CO2 must be excreted somehow, so the blood takes it from the cytoplasm in our respiring cells, and transports it to our lungs, when we subsequently exhale it out of our bodies.
diffusion in capillaries
oxygen goes into your lungs and then co2 comes out when mixed with a substance in your lungs.
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.
respiratory system and the harmul effects of CO2
They Collect CO2 from Your Lungs as They Are Constantly being pumped around the body therefore collecting Co2 Emissions every time they pass to your lungs.
O2 and Co2, but we breathe out the Co2 again + the O2 which is converted in more Co2
hmm
co2
The lungs are an exchange point where CO2 leaves and O2 enters the blood
CO2 Carbon dioxide
veins take the CO2 back to the lungs as a waste.
In the lungs, the blood receives O2 while getting rid of CO2
to expel CO2 from your body and to allow O2 into your bloodstream
